   A 3D Monte Carlo calculation of the inverse Compton emission from the Sun and stars in presence of magnetic and electric fields

   M. N. Mazziotta🇮🇹

   The solar steady emission in gamma rays is due to the interactions of Galactic cosmic rays with the solar atmosphere and with the low-energy solar photon field via inverse Compton scattering. The emission is sensitive to the magnetic field nearby the Sun and to the cosmic-ray transport in the magnetic field in the inner solar system. Modeling the inverse Compton emission in the presence of a magnetic field is therefore crucial to better interpret the observations. In a previous work we have presented a comprehensive calculation of the secondary productions due to the collision of cosmic rays with the solar atmosphere in presence of magnetic fields. In this paper, we present a general approach to calculate the (anisotropic) inverse Compton scattering in a 3D Monte Carlo simulation, also in presence of magnetic and electric fields. After a short review of the scattering process of photons with electrons, examples of inverse Compton emission are presented, including the predictions for the Sun.

   Extending the LCSR method to the electromagnetic pion form factor at low momenta using QCD renormalization-group summation

   Cesar Ayala🇨🇱 · S. V. Mikhailov🇷🇺 · A. V. Pimikov🇷🇺

   We obtain the electromagnetic pion form factor (emFF) $F_{\pi }$ for spacelike mid-range of momentum transfer in QCD. We use renormalization group (RG) summation within the light cone sum rules (LCSRs) to obtain the QCD radiative corrections to the $F_{\pi }$ and involve contributions of the leading twist 2 and, twists 4, 6. The additional conditions to apply here this RG summation are discussed in details. The strong coupling constants in this approach are free of Landau singularities, which allows one to go down to the lower transferred momentum $Q^2$. The prediction of the calculations performed reproduces the experimental data below/around $Q^2=1$~GeV${}^2$ significantly better than analogous predictions based on a fixed-order power-series expansion in the standard QCD.

   Subthreshold poles in electron-positron annihilation. D\bar{D} final states

   Peter Lichard🇨🇿

   We show that the $\psi (2\mathrm{S})$ subthreshold pole influences the cross section of the electron-positron annihilation into the ${\mathrm{D}}^{+}{\mathrm{D}}^{-}$ and \mathrm D^0\bar\mathrm D^0 final states. We perform a fit to the merged BES \cite{bes2008} and BESIII \cite{besiii2024} data, providing the cross section for $e^{+}{e}^{-}$ annihilation into those final states. The statistical significance of the $\psi (2\mathrm{S})$ as a subthreshold pole is 8.2$\sigma$. A fit assuming it and seven resonances excels with the fit quality characterized by ${\chi }^2/\mathrm{NDF}=240.4/284$, which means a $p$-value of 97\%.

   Radiative B to tensor meson decays at NLO in SCET

   Arslan Sikandar🇵🇰 · M. Jamil Aslam🇵🇰

   The radiative $B$ to tensor $\left(K_2^{\ast }(1430),f_2(1270),a_2(1230)\right)$ meson decays are studied at next-to-leading order (NLO) in soft-collinear effective theory (SCET). The SCET allows the systematic treatment of factorizable and non-factorizable contributions along with the resummation of large perturbative logarithms. We performed a two step matching and determined the soft-overlap function ${\zeta }_T^{\perp }$ and branching ratios for these $B$ to tensor meson decays. In the case of $B\to K_2^{\ast }(1430)\gamma$, the numerical value of the branching ratio lies close to its experimental measurements. The estimated values of the branching ratios of CKM suppressed decays $B\to \left(a_2(1230),f_2(1270)\right)\gamma$ are significant small compared to that of $B\to K_2^{\ast }(1430)\gamma$, but still could be measured in some ongoing and future $B$ physics experiments.

   Investigating charmed hybrid baryons via QCD sum rules

   Hui-Min Yang🇨🇳 · Xuan Luo🇨🇳 · Hua-Xing Chen🇨🇳 · Wei Chen🇨🇳

   We investigate charmed hybrid baryons using the QCD sum rule method within the framework of heavy quark effective theory. We construct twenty-eight interpolating currents for charmed hybrid baryons, seven of which are employed in QCD sum rule analyses of nineteen states with quark-gluon configurations $qqcg$, $qscg$, and $sscg$ ($q=u/d$). The masses of the lowest-lying charmed hybrid baryons in the $SU(3)$ flavor $6_F$ representation are calculated to be $M_{{\Sigma }_{cg}(1/2^{+})}=3.36_{-0.26}^{+0.27}\mathrm{GeV}$, $M_{{\Xi }_{cg}^{\prime }(1/2^{+})}=3.59\pm 0.20\mathrm{GeV}$, and $M_{{\Omega }_{cg}(1/2^{+})}=3.82\pm 0.21\mathrm{GeV}$. We propose that future experiments search for these states via their $P$-wave decay channels $N{D}^{(\ast )}$, $\Lambda D^{(\ast )}$, and $\Xi D^{(\ast )}$, respectively. Such investigations would provide valuable insight into the role of gluonic excitations in hadron structure.

   The mass of the lightest gluelump

   Cesar Ayala🇨🇱 · Antonio Pineda🇪🇸

   We give the most up-to-date determinations of the normalization of the leading renormalons of the pole mass, the singlet static potential, the octet static potential, and the gluelump energy. They read $Z_m^{\mathrm{MS}}=-Z_{V_s}^{\mathrm{MS}}/2=\{0.604(17),0.551(20)\}$, $Z_{V_o}^{\mathrm{MS}}=\{0.136(8),0.121(13)\}$, and $Z_A^{\mathrm{MS}}=\{-1.343(36),-1.224(43)\}$, for $n_f=0$ and $n_f=3$ respectively. We obtain two independent renormalization group invariant and renormalization scale independent determinations of the energy of the ground state gluelump in the principal value summation scheme: ${\Lambda }_B^{\mathrm{PV}}=2.47(9)r_0^{-1}$ and ${\Lambda }_B^{\mathrm{PV}}=2.38(11)r_0^{-1}$. They combine in ${\Lambda }_B^{\mathrm{PV}}=2.44(7)r_0^{-1}$.

   Estimating of CP Violation in $B_c\to B{K}^0+B{\bar{K}}^0\to B{\pi }^{\pm }{e}^{\mp }{\nu }_e$ Decays

   Xiao-Dong Cheng🇨🇳 · Zhen-Lu Weng🇨🇳 · Ying-Ying Fan🇨🇳 · Ru-Min Wang🇨🇳

   In this paper, we investigate the CP asymmetries ${\mathcal{A}}_{CP}^{pm}$ and ${\mathcal{A}}_{CP}^{mp}$ in $B_c^{\pm }\to B^{\pm }{K}^0+B^{\pm }{\bar{K}}^0\to B^{\pm }{\pi }^{\pm }{e}^{\mp }{\nu }_e$ and $B_c^{\pm }\to B^{\pm }{K}^0+B^{\pm }{\bar{K}}^0\to B^{\pm }{\pi }^{\mp }{e}^{\pm }{\nu }_e$ decays, both of them consist of three parts: the indirect CP violations in $K^0-{\bar{K}}^0$ mixing $A_{CP,mix}^{pm}$ and $A_{CP,mix}^{mp}$, the direct CP violations in $B_c$ decay $A_{CP,dir}^{pm}$ and $A_{CP,dir}^{mp}$, the new CP violation effects $A_{CP,int}^{pm}$ and $A_{CP,int}^{mp}$, which originate from the interference between the amplitude of the $B_c^{-}\to B^{-}{K}^0({\bar{K}}^0)\to B^{-}{\pi }^{-}{e}^{+}{\nu }_e({\pi }^{+}{e}^{-}{\bar{\nu }}_e)$ decay with the difference between the oscillating effect of $K^0\to {\bar{K}}^0$ and that of ${\bar{K}}^0\to K^0$. The strong phase differences of the direct CP asymmetries $A_{CP,dir}^{pm}$ and $A_{CP,dir}^{mp}$ arising from $K^0-{\bar{K}}^0$ mixing parameters. ${\mathcal{A}}_{CP}^{pm}$ and ${\mathcal{A}}_{CP}^{mp}$ are of the order $\mathcal{O}(10^{-4})$ and $\mathcal{O}(10^{-3})$, respectively. The new CP violation effect ${\mathcal{A}}_{CP,int}^{pm}$ plays a dominant role in ${\mathcal{A}}_{CP}^{pm}$, the CP asymmetry ${\mathcal{A}}_{CP}^{mp}$ is dominated by the indirect CP violation ${\mathcal{A}}_{CP,mix}^{mp}$, so the CP asymmetry ${\mathcal{A}}_{CP}^{pm}$ provides an ideal place to study the new CP violation effect. We derive another two asymmetry observables ${\mathcal{A}}_{CP}^{pp}$ and ${\mathcal{A}}_{CP}^{mm}$, which are dominated by $K^0-{\bar{K}}^0$ mixing. The observables ${\mathcal{A}}_{CP}^{pm}$, ${\mathcal{A}}_{CP}^{mp}$, ${\mathcal{A}}_{CP}^{pp}$ and ${\mathcal{A}}_{CP}^{mm}$ are hopefully to be marginally observed at the LHC experiment and the HL-LHC experiment.

   Asymptotic gauge symmetry and UV extension of the nonperturbative coupling in holographic QCD

   Guy F. de Teramond🇨🇷 · Arpon Paul🇺🇸 · Hans Gunter Dosch🇩🇪 · Stanley J. Brodsky🇺🇸 · Alexandre Deur🇺🇸 · Tianbo Liu🇨🇳 · Raza Sabbir Sufian🇺🇸

   We extend our recent analytic study of the strong coupling ${\alpha }_{\mathrm{eff}}$ in the nonperturbative and near-perturbative regimes~\cite{deTeramond:2024ikl} by imposing rigorous renormalization-group results from asymptotically free gauge theories at $Q^2\to \infty$. The asymptotic boundary conditions modify the scaling properties of ${\alpha }_{\mathrm{eff}}$ at large values of the momentum transfer $Q^2$, and lead to a scale-dependent confinement strength $\kappa (Q^2)$. This requires that both $\kappa (Q^2)$ and ${\alpha }_{\mathrm{eff}}\left(Q^2,\kappa (Q^2)\right)$ remain holomorphic in the complex $Q^2$ plane, except at the physical cuts associated with the heavy-quark thresholds and the singularity flow trajectory studied in~\cite{deTeramond:2024ikl}. For color $SU(3)$, a precise connection is found between the scaling exponent of $\kappa (Q^2)$ in the ultraviolet, the value of the infrared fixed point of the strong coupling, and the number of flavors in agreement with observations. The nonperturbative analytic model gives an accurate description of the strong coupling at all scales, up to the highest available data.

   The Bubble Wall Velocity in Local Thermal Equilibrium and Energy Budget with Full Effective Potential

   Zongguo Si🇨🇳 · Hongxin Wang🇨🇳 · Lei Wang🇨🇳 · Yang Xiao🇨🇳 · Yang Zhang🇨🇳

   We develop a framework based on the full one-loop finite-temperature effective potential model, within which the bubble wall velocity is calculated using the local thermal equilibrium (LTE) approximation, and the kinetic energy fraction $K$ is computed directly. In cosmological phase transitions, these quantities play a critical role in determining the resulting gravitational wave signals. Using the xSM as a benchmark model, we compute the peak gravitational wave spectra under different methods for determining the wall velocity and the kinetic energy fraction $K$, and compare these results to those obtained using the commonly employed bag model. Within the scanned parameter space, we find: (1) Deflagration is the most prevalent mode of fluid motion.(2) Gravitational wave spectra based on the full effective potential with LTE-derived wall velocity and integrated $K$ can differ significantly from those using the bag model with fitted $K$. In the deflagration regime, discrepancies reach up to 48\% in peak frequency and 90\% in amplitude.(3) The bag model provides a good approximation to the full equation of state in many cases. Notably, in deflagration scenarios with input wall velocity, the gravitational wave spectra obtained from the bag model more closely resemble the LTE-based results than those derived using the full potential with this input wall velocity.

    The nonleptonic decays ${\Xi }_{cc}^{++}\to {\Xi }_c^{(\prime )+}{\pi }^{+}$ within the nonrelativistic quark model

    Yu-Shuai Li🇨🇳

    In this work, we study the nonleptonic decays ${\Xi }_{cc}^{++}\to {\Xi }_c^{(\prime )+}{\pi }^{+}$ with considering ${\Xi }_c-{\Xi }_c^{\prime }$ mixing. The relevant decay amplitudes are evaluated within the framework of nonrelativistic quark model, combining the baryon spatial wave functions adopted from solving the Schrödinger equation with a nonrelativistic potential. With the mixing angle ranging $\theta \in (-18.2^{\circ },-14.3^{\circ })$, we successfully reproduce the measured ratio $R=\mathcal{B}[{\Xi }_{cc}^{++}\to {\Xi }_c^{\prime +}{\pi }^{+}]/\mathcal{B}[{\Xi }_{cc}^{++}\to {\Xi }_c^{+}{\pi }^{+}]$ reported by the LHCb Collaboration. Furthermore, we estimate the branching fractions as $\mathcal{B}[{\Xi }_{cc}^{++}\to {\Xi }_c^{+}{\pi }^{+}]=(3.2\sim 4.3)\%$ and $\mathcal{B}[{\Xi }_{cc}^{++}\to {\Xi }_c^{\prime +}{\pi }^{+}]=(4.2\sim 6.0)\%$, and the asymmetry parameters as $\alpha [{\Xi }_{cc}^{++}\to {\Xi }_c^{+}{\pi }^{+}]=(-0.80\sim -0.81)$ and $\alpha [{\Xi }_{cc}^{++}\to {\Xi }_c^{\prime +}{\pi }^{+}]=(-0.61\sim -0.62)$. The measurements of absolute branching fractions and asymmetry parameters by the ongoing LHCb and Belle II experiments will be helpful for further testing our numerical results and confirming the mixing angle.

    Gauge symmetry breaking with $S^2$ extra dimensions

    Kento Asai🇯🇵 · Yuki Honda🇯🇵 · Hiroki Ishikawa🇯🇵 · Joe Sato🇯🇵 · Yasutaka Takanishi🇯🇵

    We consider symmetry breaking of arbitrary gauge groups on a six-dimensional space-time which consists of a four-dimensional Minkowski space-time $M^4$ and a two-dimensional sphere $S^2$. We expand the gauge fields in the presence of a non-trivial background unique to $S^2$. We analyze Kaluza-Klein(KK) modes of the gauge fields and derive the mass spectrum of the KK modes. We found that the gauge fields (not) commuting with the background fields (do not) remain symmetry operators in four dimensions. We also discuss the mass spectrum of the extra-dimensional components of the gauge fields and identify a physical scalar $\varphi$ and a Nambu-Goldstone mode $\chi$. As a result, we obtain a method to break gauge symmetry due to the nontrivial solution for gauge fields which is a unique feature of $S^2$.

    Revisiting Flavor Model and Leptogenesis

    Takaaki Nomura🇨🇳 · Yusuke Shimizu🇯🇵 · Towa Takahashi🇯🇵

    We revisit a supersymmetric flavor model based on the symmetries $SU(2{)}_L\times A_4\times Z_3\times U(1{)}_R$, which extends the original Altarelli and Feruglio construction by introducing flavon and driving superfields responsible for the spontaneous breaking of the flavor symmetry in order to obtain non-zero reactor angle. The vacuum alignments of flavon fields are achieved through the minimization of the scalar potential derived from the superpotential. This setup leads to specific mass matrices for the charged leptons and neutrinos that are consistent with current experimental data, including the measured values of the lepton mixing angles and neutrino mass squared differences. We investigate whether the model can simultaneously accommodate successful thermal leptogenesis. In particular, we analyze the CP asymmetry generated in the decay of heavy Majorana neutrinos, the resulting lepton asymmetry, and its conversion to the baryon asymmetry through the electroweak sphalerons. However the CP asymmetry is zero, since the Dirac neutrino mass matrix is simple texture in the leading order for our model. Then we consider the next-to-leading order in Yukawa interactions of the Dirac neutrinos. Therefore, we can realize the baryon asymmetry of the universe at the present universe. By numerically scanning the parameter space, we identify the regions consistent with both neutrino oscillation data and the observed baryon asymmetry. In the specific case such that one of the couplings for the right-handed Majorana neutrinos is real parameter, the predicted lightest neutrino mass is at least $5$ meV and $15$ meV for the normal and inverted neutrino mass hierarchies, respectively. In addition, the range of the Majorana phases may be tested in future experiments.

    Classical Analysis of Non-Coherent Dark Matter to Photon Conversion in a Resonant Cavity

    Puxian Wei🇨🇳 · Ruifeng Zheng🇨🇳 · Qiaoli Yang🇨🇳

    Both axion and dark photon dark matter are among the most promising candidates of dark matter. What we know with some confidence is that they exhibit a small velocity distribution $\delta v\lesssim v\sim 10^{-3}$c. In addition, their mass is small, resulting in a long de Broglie wavelength and a high particle number density. Their phase space distribution contains many uncertainties, so they could give rise to either a coherent or noncoherent wave on the laboratory scale. In this paper, we demonstrated that a resonant cavity can enhance noncoherent axion-to-photon or dark photon-to-photon transitions, and the resulting power is the same as in the coherence case. The classical picture explanation is that a cavity can resonant with multiple different sources simultaneously. This aligns with the quantum perspective, where the cavity boosts dark matter particles transitioning into photons similarly to the Purcell effect. This effect increases the density of states near resonance, regardless of the coherence nature of dark matter. Certainly, the induced microwave signals in a cavity are also non-coherent, and in such case, a single-photon readout may be required.

    A Roadmap for neutrino charge assignments in $U(2{)}_F$ Flavor Models: Implications for LFV processes and leptonic anomalous magnetic moments

    A. Giarnetti🇮🇹 · S. Marciano🇮🇹 · D. Meloni🇮🇹 · M. Rettaroli🇮🇹

    We build upon a simple $U(2{)}_F$ model of flavor, in which all fermion masses and mixing hierarchies arise from powers of two small parameters controlling $U(2{)}_F$ breaking. In the original formulation, an isomorphism to the discrete $D_6\times U(1{)}_F$ symmetry was invoked to generate a Majorana neutrino mass term. Here, we retain the successful features of that model for the charged leptons and quarks, while exploring alternative neutrino charge assignments within the $U(2{)}_F$ framework. This approach allows us to generate Majorana neutrino masses via the see-saw mechanism without introducing any additional symmetries nor invoking any isomorphism. We further examine the implications of our models for Lepton Flavor Violating (LFV) decays, analyzing the processes $\mu \to e\gamma$, $\tau \to \mu \gamma$ and $\tau \to e\gamma$ and their connection with the leptonic anomalous magnetic moments. We show that within the Standard Model Effective Field Theory (SMEFT) approach the current limits on the branching ratios of $\mu \to e\gamma$ LFV decays obtained in our $U(2{)}_F$ models are not compatible with the central value of the recent measurement of the $(g-2{)}_{\mu }$, thereby suggesting that either $(g-2{)}_{\mu }$ must be very close to the Standard Model predictions, as the latest experimental and theoretical results seem to suggest, or the invoked flavor symmetry is not appropriate to describe an anomalous muon magnetic moment.

    Precision Unitarity Calculations in Inflationary Models

    Thomas Steingasser🇺🇸 · Mark P. Hertzberg🇺🇸 · David I. Kaiser🇺🇸

    We revisit perturbative unitarity in scalar field inflation with a nonminimal coupling, with Higgs inflation serving as the most prominent example. Although such models are phenomenologically successful, it is critical to examine whether or not unitarity violations spoil their theoretical self-consistency. The analysis of these issues has so far typically relied on order-of-magnitude estimates of scattering amplitudes, which are appropriate for generic parameters. It is not evident that these methods apply to scenarios relying on a near-critical inflationary potential, for which an interplay of both small scalar self-couplings and nonminimal couplings could partially alleviate the unitarity issues. To allow for an exploration of this possibility, we consider the full $S$-matrix for the relevant scattering processes, taking into account important phase space volume factors, leading to a precise evaluation of the cut-off scale. In the single-field case, we demonstrate that near-criticality raises the cut-off scale considerably, compared to previous estimates. In the multifield case, momentum-dependent self-interactions in the kinetic sector lower the cut-off compared to the single-field case to a value comparable to but slightly larger than previous estimates. We carefully study both the single-field and multifield cases in metric and metric-affine (Palatini) formulations of gravity, as well as introduce a new phenomenologically viable model with a canonical kinetic term and a significantly raised cut-off, and discuss the importance of background field effects.

    Dispersion relation of the neutrino plasma: Unifying fast, slow, and collisional instabilities

    Damiano F. G. Fiorillo🇩🇪 · Georg G. Raffelt🇩🇪

    In neutrino-dense astrophysical environments, these particles exchange flavor through a coherent weak field, forming a collisionless neutrino plasma with collective flavor dynamics. Instabilities, which grow and affect the environment, may arise from neutrino-neutrino refraction alone (fast limit), vacuum energy splittings caused by masses (slow limit), or neutrino-matter scattering (collisional limit). We present a comprehensive analytical description of the dispersion relation governing these unstable modes. Treating vacuum energy splittings and collision rates as small perturbations, we construct a unified framework for fast, slow, and collisional instabilities. We classify modes into gapped, where collective excitations are already present in the fast limit but rendered unstable by slow or collisional effects, and gapless, which are purely generated by these effects. For each class, we derive approximate dispersion relations for generic energy and angle distributions, which reveal the order of magnitude of the growth rates and the nature of the instabilities without solving directly the dispersion relation. This approach confirms that slow and collisionally unstable waves generally grow much more slowly than they oscillate. Consequently, the common fast-mode approximation of local evolution within small boxes is unjustified. Even for fast modes, neglecting large-distance propagation of growing waves, as usually done, may be a poor approximation. Our unified framework provides an intuitive understanding of the linear phase of flavor evolution across all regimes and paves the way for a quasi-linear treatment of the instability's nonlinear development.

    We show that solutions to the strong CP problem based on modular invariance can be extended to incorporate features that appear in string compactifications: quarks with mostly positive modular weights and non-trivial gauge kinetic functions. This requires assuming that singularities and zeroes only appear at special points, such as decompactification limits. We discuss the impact of these assumptions on string gauge unification.

    Minimal Plateau Inflation in light of ACT DR6 Observations

    Md Riajul Haque🇮🇳 · Debaprasad maity🇮🇳

    We explore a class of minimal plateau inflationary models constrained by the latest cosmological observations from ACT DR6, Planck 2018, BICEP/Keck 2018, and DESI, collectively referred to as P-ACT-LB-BK18. These models, characterized by a non-polynomial potential, are analyzed using both inflationary and post-inflationary reheating dynamics, and the limits on the viable model parameter space are obtained. Our results show that the minimal model with matter-like post inflationary reheating phase remains consistent with current data at both $1\sigma$ and $2\sigma$ levels. The inflaton potential's exponent $n$ and reheating epoch are intertwined in that upon its increase, corresponding to the stiffer reheating equation of state, the viable model parameter space in accordance with ACT shrinks, which is further facilitated by the primordial gravitational waves (PGWs) overproduction. We further explored a supergravity-inspired extension of the model under study with similar results, but with tighter constraints on the model parameters. These results emphasize the importance of jointly analyzing CMB data and reheating physics to test inflationary models.

    Lattice QCD Benchmark of Proton Helicity and Flavor-Dependent Unpolarized Transverse Momentum-Dependent Parton Distribution Functions at Physical Quark Masses

    Dennis Bollweg🇺🇸 · Xiang Gao🇺🇸 · Swagato Mukherjee🇺🇸 · Yong Zhao🇺🇸

    We present the first lattice QCD calculations of the isovector helicity transverse momentum-dependent parton distribution function (TMDPDF) and the flavor-dependent unpolarized TMDPDFs for up and down quarks in the proton. Our computations utilize domain-wall fermion discretization with physical quark masses. Employing Coulomb-gauge-fixed quark correlation functions within the large-momentum effective theory framework, we access nonperturbative transverse quark separations $b_T$ up to approximately 1 fm, corresponding to transverse momenta as low as 200 MeV. Based on the quasi-TMD factorization theorem, we construct renormalization-group-invariant ratios that are equal to the corresponding light-cone TMDPDF ratios. At moderate $x$, our results reveal that the isovector helicity and unpolarized TMDPDFs exhibit nearly identical transverse structure up to a normalization factor, and the unpolarized distributions display only mild flavor dependence. These findings not only support key trends observed in recent global analyses but also provide robust, nonperturbative constraints that can distinguish between different parameterizations. This work establishes a first-principles benchmark for TMDPDFs, offering valuable input for ongoing and future experimental efforts to map the proton's three-dimensional structure.

    Bridging reaction theory and nuclear structure in ${\pi }^{\pm }$-${}^{48}$Ca scattering

    Viacheslav Tsaran🇩🇪 · Francesco Marino🇩🇪 · Sonia Bacca🇩🇪 · Francesca Bonaiti🇺🇸 · Marc Vanderhaeghen🇩🇪

    We extend the pion-nucleus multiple-scattering framework to include detailed second-order rescattering dynamics for nuclei with non-zero isospin. To account for intermediate charge-exchange and nucleon spin-flip effects, we develop a scattering potential that depends on the one- and two-body densities of the target nucleus. We compute one-body densities from coupled-cluster theory and two-body densities within the Hartree-Fock approximation. To estimate theoretical uncertainties, we employ modern nuclear Hamiltonians derived from chiral effective field theory. While the sensitivity to nuclear structure details is mild, second-order corrections are found to be sizeable and essential for accurately reproducing differential cross sections measured in ${\pi }^{\pm }$-${}^{48}$Ca elastic scattering within the $\Delta (1232)$-resonance region

    Constraints on maximum neutron star mass from proto-neutron star evolution

    Deepak Kumar🇮🇳 · Tuhin Malik🇵🇹 · Hiranmaya Mishra🇮🇳 · Constança Providência🇵🇹

    A proto-neutron star (PNS) gets formed after a successful supernova when the stellar remnant decouples from the ejecta. In this study, we explore a relativistic framework for the finite-temperature $\beta$-equilibrium limit of equation of state (EOS), constrained via a Bayesian inference methodology. The EOS is constrained by minimal approximations on a few nuclear saturation properties, low-density pure neutron matter constraints from chiral effective field theory, and a neutron star (NS) maximum mass greater than 2.0 $M_{\odot }$. Two sets of EOS derived from the relativistic mean field model for nucleonic and hyperonic matter constrained by a Bayesian inference calculation at the zero temperature limit are used. The thermal adiabatic index (${\Gamma }_{\mathrm{Th}}$) is calculated as a function of the baryonic density across several temperatures for both the sets. Our results suggest that the maximum NS mass is of the order of 2.15 $M_{\odot }$ if hyperons are present. In addition, the present study suggests that an observation of NS with mass larger than $2.2M_{\odot }$ can indirectly indicates the absence of hyperons in its core. The deleptonization of hyperonic PNS reduces the stellar maximum mass rendering the PNS exceeding the zero temperature maximum stellar (baryonic) mass limit becomes metastable which is prone to collapse into a black hole while PNS below such a mass threshold evolves to a stable NS.

    Microscopic constraints for the equation of state and structure of neutron stars: a Bayesian model mixing framework

    A. C. Semposki🇺🇸 · C. Drischler🇺🇸 · R. J. Furnstahl🇺🇸 · D. R. Phillips🇺🇸

    Bayesian model mixing (BMM) is a statistical technique that can combine constraints from different regions of an input space in a principled way. Here we extend our BMM framework for the equation of state (EOS) of strongly interacting matter from symmetric nuclear matter to asymmetric matter, specifically focusing on zero-temperature, charge-neutral, $\beta$-equilibrated matter. We use Gaussian processes (GPs) to infer constraints on the neutron star matter EOS at intermediate densities from two different microscopic theories: chiral effective field theory ($\chi$EFT) at baryon densities around nuclear saturation, $n_B\sim n_0$, and perturbative QCD at asymptotically high baryon densities, $n_B⩾20n_0$. The uncertainties of the $\chi$EFT and pQCD EOSs are obtained using the BUQEYE truncation error model. We demonstrate the flexibility of our framework through the use of two categories of GP kernels: conventional stationary kernels and a non-stationary changepoint kernel. We use the latter to explore potential constraints on the dense matter EOS by including exogenous data representing theory predictions and heavy-ion collision measurements at densities $⩾2n_0$. We also use our EOSs to obtain neutron star mass-radius relations and their uncertainties. Our framework, whose implementation will be available through a GitHub repository, provides a prior distribution for the EOS that can be used in large-scale neutron-star inference frameworks.

    Examining Quintessence Models with DESI Data

    Zahra Bayat🇺🇸 · Mark P. Hertzberg🇺🇸

    We examine data from the Dark Energy Spectroscopic Instrument (DESI) collaboration which has implications for the nature of dark energy. We consider classes of models that manifestly obey the null energy condition, with a focus on quintessence models. We find that hilltop potentials and exponential potentials provide modest improvement compared to a cosmological constant, but the statistical evidence is only marginal at this stage. We correct some analyses in the existing literature which attempted to compare some quintessence models to the data, giving an overly positive result.

    On the Analysis Dependence of DESI Dynamical Dark Energy

    Eoin Ó Colgáin🇮🇪 · Saeed Pourojaghi🇮🇷 · M. M. Sheikh-Jabbari🇮🇷

    We continue scientific scrutiny of the DESI dynamical dark energy (DE) claim by explicitly demonstrating that the result depends on the analysis pipeline. Concretely, we define a likelihood that converts the $w_0{w}_a$CDM model back into the (flat) $\Lambda$CDM model, which we fit to DESI constraints on the $\Lambda$CDM model from DR1 Full-Shape (FS) modelling and BAO. We further incorporate CMB constraints. Throughout, we find that $w_0$ and $w_a$ are within $1\sigma$ of the $\Lambda$CDM model. Our work makes it explicit that, in contrast to DR1 and DR2 BAO, there is no dynamical DE signal in FS modelling, even when combined with BAO and CMB. Moreover, one confirms late-time accelerated expansion today $(q_0<0)$ at $\gtrsim 3.4\sigma$ in FS modelling + BAO. On the contrary, DR1 and DR2 BAO fail to confirm $q_0<0$ under similar assumptions. Our analysis highlights the fact that trustable scientific results should be independent of the analysis pipeline.

    Testing the cosmological principle on gigaparsec scales

    Xin Wang🇨🇳 · Zhiqi Huang🇨🇳

    Recent observational analyses have suggested possible evidence of hemisphere asymmetry in cosmological datasets. Parameterizations of this kind place observers in a privileged position-specifically on the plane that divides the two hemispheres. To quantify potential deviations from the cosmological principle without presuming a special location, we develop a stochastic framework that parametrizes departures from statistical homogeneity and isotropy. The near-uniform temperature of the cosmic microwave background indicates that anisotropy is negligible (at the $\lesssim 10^{-5}$ level) on the last scattering surface. This serves as a zero boundary condition, enabling the construction of an orthogonal basis of functions below the recombination redshift. Within this basis, we expand the relative deviation from the Hubble diagram of isotropic models (such as $\Lambda$CDM or $w_0{w}_a$CDM) in a hierarchy of increasing resolution. Applying this approach, we test the cosmological principle using Type Ia supernovae, strong lensing time delays, and gravitational-wave standard sirens. For the class of large-scale anisotropies and low-order radial variations described by this framework, the current datasets are found to be consistent with statistical homogeneity and isotropy on gigaparsec scales.

    Comment on "An implementation of neural simulation-based inference for parameter estimation in ATLAS''

    Prasanth Shyamsundar🇺🇸

    The paper titled "An implementation of neural simulation-based inference for parameter estimation in ATLAS" by the ATLAS collaboration (arXiv:2412.01600v1 [hep-ex]) describes the implementation of neural simulation-based inference for a measurement analysis performed by ATLAS. The uncertainties in the analysis arising from the finiteness of the simulated datasets are estimated using a novel double-bootstrapping technique described in that work. In the present comment, it is claimed and demonstrated, using a toy example, that the double-bootstrapping technique does not actually capture the aforementioned uncertainties.

    The Gauge Theory Bootstrap: Predicting pion dynamics from QCD

    Yifei He🇫🇷 · Martin Kruczenski🇺🇸

    The Gauge Theory Bootstrap [arXiv:2309.12402, arXiv:2403.10772] computes the strongly coupled pion dynamics by considering the most general scattering matrix, form factors and spectral densities and matching them with perturbative QCD at high energy and with weakly coupled pions at low energy. In this work, we show that further constraints on the spectral densities significantly reduce the possible solutions to a small set of qualitatively similar ones. Quantitatively, the precise solution is controlled by the asymptotic value of the form factors and SVZ sum rules. We also introduce an iterative procedure that, starting from a generic feasible point, converges to a unique solution parameterized by the UV input. For the converged solution we compute masses and widths of resonances that appear, scattering lengths and effective ranges of partial waves, low energy coefficients in the effective action. Additionally, we use these results to discuss the thermodynamics of a pion gas including pair correlations of pions with same and opposite charge.

    Occurrence of fast neutrino flavor conversions in QCD phase-transition supernovae

    Zewei Xiong🇩🇪 · Meng-Ru Wu🇹🇼 · Noshad Khosravi Largani🇵🇱 · Tobias Fischer🇵🇱 · Gabriel Martínez-Pinedo🇩🇪

    Core-collapse supernovae undergoing a first-order quantum chromodynamics (QCD) phase transition experience the collapse of the central proto-neutron star that leads to a second bounce. This event is accompanied by the release of a second neutrino burst. Unlike the first stellar core bounce neutrino burst which consists exclusively of electron neutrinos, the second burst is dominated by electron antineutrinos. Such a condition makes QCD supernovae an ideal site for the occurrence of fast neutrino flavor conversion (FFC), which can lead to rapid flavor equilibration and significantly impact the related neutrino signal. In this work, we perform a detailed analysis of the conditions for fast flavor instability (FFI) around and after the second neutrino burst in QCD phase transition supernova models launched from 25~$M_{\odot }$ and 40~$M_{\odot }$ progenitor models. We evaluate the relevant instability criteria and find two major phases of FFC. The first phase is closely associated with the collapse and the rapidly expanding shock wave, which is a direct consequence of the proto-neutron star collapse due to the phase transition. The second phase takes place a few milliseconds later when electron degeneracy is restored near the proto-neutron star surface. We also characterize the growth rate of FFI and estimate its impact on the evolution of the neutrino flavor content. The potential observational consequences on neutrino signals are evaluated by comparing a scenario assuming complete flavor equipartition with other scenarios without FFC. Finally, we investigate how FFC may influences $r$-process nucleosynthesis associated with QCD phase transition driven supernova explosions.

    Study of $p_{\mathrm{T}}$-differential radial flow in blast-wave model

    Swati Saha🇮🇳 · Ranbir Singh🇮🇳 · Bedangadas Mohanty🇮🇳

    The transverse momentum-differential radial flow observable $v_0(p_{\mathrm{T}})$, recently proposed and measured by the ATLAS and ALICE collaborations, provides a novel tool to probe radial expansion dynamics in high-energy heavy-ion collisions. In this work, we conduct a detailed study of $v_0(p_{\mathrm{T}})$ using a blast-wave model that incorporates hydrodynamic-like expansion and thermal emission. We introduce event-by-event fluctuations in the transverse expansion velocity and kinetic freeze-out temperature using Gaussian probability distributions. Our results show that increasing the mean expansion velocity leads to a clear mass ordering in $v_0(p_{\mathrm{T}})$, while fluctuations in both expansion velocity and freeze-out temperature significantly enhance the magnitude of $v_0(p_{\mathrm{T}})$, particularly at higher $p_{\mathrm{T}}$. We fit blast-wave model calculations for identified hadrons ($\pi$, K, and p) to recent ALICE data from Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV using a Bayesian parameter estimation framework. The extracted mean transverse expansion velocity decreases, while the kinetic freeze-out temperature increases, from central to peripheral collisions. Additionally, the freeze-out temperatures inferred from $v_0(p_{\mathrm{T}})$ are systematically higher than those obtained from conventional $p_{\mathrm{T}}$-spectra fits, likely due to the reduced sensitivity of $v_0(p_{\mathrm{T}})$ to resonance decay contributions.

    Mirror Symmetry and Spinor-Vector Duality: A Top-Down Approach to the Swampland Program

    Alon E. Faraggi🇬🇧

    Mirror symmetry is one of the celebrated developments in pure mathematics that arose from an initial observation in worldsheet string constructions. The profound implications of mirror symmetry in the Effective Field Theory (EFT) limit of string compactifications was subsequently understood. In particular, it proved to be an exceptionally useful tool in the field of enumerative geometry. Spinor-Vector Duality (SVD) is an extension of mirror symmetry that can be readily understood in terms of the moduli parameters of toroidal heterotic-string compactifications, which include the metric, the anti-symmetric ternsor field and the Wilson-line moduli. While mirror symmetry corresponds to maps of the internal moduli parameters, {ı.e.} the metric and the anti-symmetric tensor field, SVD corresponds to maps of the Wilson-line moduli. Similar to mirror symmetry the imprint of SVD in the EFT limit can serve as a tool to study the properties of complex manifolds with vector-bundles. Spinor-Vector Duality motivates a top--down approach to the "Swampland" program, by studying the imprint of the symmetries of the worldsheet ultra-violet complete string constructions in the EFT limit. It is conjectured that SVD provides a demarcation line between (2,0) EFTs that possess an ultra-violet complete embedding in string theory versus those that do not.

    Comparative study of the strong backreaction regime in axion inflation: the effect of the potential

    Joanes Lizarraga🇪🇸 · Carmelo López-Mediavilla🇪🇸 · Ander Urio🇪🇸

    Recent works have demonstrated the necessity of capturing the local inhomogeneous physics in axion inflation, and showed new genuine features, most notably the extension of the inflationary period dictated by an electromagnetic slow-roll phase. In this work, we further investigate the model by performing a systematic study of the effect of the inflationary potential in the dynamics during the strong backreaction regime. The results indicate that the novel features associated with the local backreaction are universal and intrinsic to the model, hence independent on the choice of inflationary potential. We find that the main quantitative differences between the different choices manifest in the lengthening of inflation. We discuss the possible observational impact of this. Finally, we assess the possible reconciliation of the homogeneous backreaction method with fully inhomogeneous lattice techniques, and obtain that the former fails to provide a correct description for the regime studied in this work.

    A frequentist view on the two-body decaying dark matter model

    Thomas Montandon🇫🇷 · Elsa M. Teixeira🇫🇷 · Adèle Poudou🇫🇷 · Vivian Poulin🇫🇷

    Decaying dark matter (DDM) has emerged as an interesting framework to extend the $\Lambda$-cold-dark-matter (LCDM) model, as many particle physics models predict that dark matter may not be stable over cosmic time and can impact structure formation. In particular, a model in which DDM decays at a rate $\Gamma$ and imprints a velocity kick $v$ onto its decay products leads to a low amplitude of fluctuations, as quantified by the parameter $S_8$, in better agreement with that measured by some weak lensing surveys. Bayesian analyses have provided mixed conclusions regarding its viability, with a reconstructed clustering amplitude only slightly below the standard LCDM value. In this paper, we contrast previous results with a frequentist analysis of Planck and SDSS BAO data. We find that the $68\%$ confidence level region corresponds to a decay half-life of $6.93_{-2.85}^{+7.88}$Gyr and a velocity kick of $1250_{-1000}^{+1450}$~km/s. These $1\sigma$ constraints strongly differ from their Bayesian counterparts, indicating the presence of volume effect in the Bayesian analysis. Moreover, we find that under the DDM model, the frequentist analysis predicts lower values of $S_8$, in agreement with those found by KiDS-1000 and DES-Y3 at $\sim 1.5\sigma$. We further show that previously derived KiDS-1000 constraints that appeared to exclude the best-fit model from Planck data were driven by priors on the primordial amplitude $A_s$ and spectral index $n_s$. When those are removed from the analysis, KiDS-1000 constraints on the DDM parameters are fully relaxed. It is only when applying Planck-informed priors on $A_s$ and $n_s$ to the KiDS-1000 analysis that one can constrain the model. We note that without such priors, the scales best measured by KiDS-1000 do not exactly match the $S_8$ kernel, so $S_8$ constraints should not be applied directly to a model in place of the full likelihood.

    Resonances in Lifetimes of AdS Oscillon

    Takaki Matsumoto🇯🇵 · Kanta Nakano🇯🇵 · Ryosuke Suda🇯🇵 · Kentaroh Yoshida🇯🇵

    Oscillons are classical oscillatory solutions with very long but finite lifetimes in real scalar field theories with appropriate potentials. An interesting feature is that resonances appear in the lifetimes of the oscillon for the initial size of the oscillon core $R_0$, which was discovered by Honda and Choptuik in the case of Minkowski space. In a previous work, oscillons in the global anti-de Sitter (AdS) space have been constructed, which we abbreviate as AdS oscillons. We present new resonance structures for the curvature radius $L$ and the core size $R_0$ in the lifetime of the AdS oscillon. We then compute exponents associated with the resonance peaks. Finally, we observe the bifurcation of the peaks due to the reflected waves.

    Lorentz Local Canonicalization: How to Make Any Network Lorentz-Equivariant

    Jonas Spinner🇩🇪 · Luigi Favaro🇧🇪 · Peter Lippmann🇩🇪 · Sebastian Pitz🇩🇪 · Gerrit Gerhartz🇩🇪 · Tilman Plehn🇩🇪 · Fred A. Hamprecht🇩🇪

    Lorentz-equivariant neural networks are becoming the leading architectures for high-energy physics. Current implementations rely on specialized layers, limiting architectural choices. We introduce Lorentz Local Canonicalization (LLoCa), a general framework that renders any backbone network exactly Lorentz-equivariant. Using equivariantly predicted local reference frames, we construct LLoCa-transformers and graph networks. We adapt a recent approach for geometric message passing to the non-compact Lorentz group, allowing propagation of space-time tensorial features. Data augmentation emerges from LLoCa as a special choice of reference frame. Our models achieve competitive and state-of-the-art accuracy on relevant particle physics tasks, while being $4\times$ faster and using $10\times$ fewer FLOPs.

    Dark Matter and Galaxy Cross-Correlations with the Cherenkov Telescope Array Observatory

    Elena Pinetti🇺🇸 · Veronika Vodeb🇸🇮 · Aurelio Amerio🇪🇸 · Alessandro Cuoco🇮🇹 · Stefano Camera🇮🇹 · Nicolao Fornengo🇮🇹 · Gabrijela Zaharijas🇸🇮

    The Cherenkov Telescope Array Observatory (CTAO) will be a ground-based Cherenkov telescope performing wide-sky surveys, ideal for anisotropy studies such as cross-correlations with tracers of the cosmic large-scale structure. Cross-correlations can shed light on high-energy $\gamma$-ray sources and potentially reveal exotic signals from particle dark matter. In this work, we investigate CTAO sensitivity to cross-correlation signals between $\gamma$-ray emission and galaxy distributions. We find that by using dense, low-redshift catalogs like 2MASS, and for integration times around 50 hours, this technique achieves sensitivities to both annihilating and decaying dark matter signals that are competitive with those from dwarf galaxy and cluster analyses.

    Cosmological impact of $\nu$DM interactions enhanced in narrow redshift ranges

    Sebastian Trojanowski🇵🇱 · Lei Zu🇵🇱

    The impact of dark matter-neutrino ($\nu$DM) interactions on cosmological perturbations has regained attention, spurred by indications of non-zero couplings from high-multipole cosmic microwave background data, weak lensing, and Lyman-$\alpha$ observations. We demonstrate that a similar observational preference is obtained if $\nu$DM interactions are primarily enhanced during a specific epoch, $z\sim (10^4-10^5)$, leading to $>3\sigma$ preference for a non-zero interaction in the combined Atacama Cosmology Telescope and cosmic shear data. This redshift-limited enhancement circumvents other cosmological and astrophysical bounds and can be achieved within a neutrino portal dark matter framework incorporating resonantly enhanced scattering rates.

    Quantum computation of hadron scattering in a lattice gauge theory

    Zohreh Davoudi🇺🇸 · Chung-Chun Hsieh🇺🇸 · Saurabh V. Kadam🇺🇸

    We present a digital quantum computation of two-hadron scattering in a $Z_2$ lattice gauge theory in 1+1 dimensions. We prepare well-separated single-particle wave packets with desired momentum-space wavefunctions, and simulate their collision through digitized time evolution. Multiple hadronic wave packets can be produced using the efficient, systematically improvable algorithm of this work, achieving high fidelity with the target initial state. Specifically, employing a trapped-ion quantum computer (IonQ Forte), we prepare up to three meson wave packets using 11 and 27 system qubits, and simulate collision dynamics of two meson wave packets for the smaller system. Results for local observables are consistent with numerical simulations at early times, but decoherence effects limit evolution into long times. We demonstrate the critical role of high-fidelity initial states for precision measurements of state-sensitive observables, such as $S$-matrix elements. Our work establishes the potential of quantum computers in simulating hadron-scattering processes in strongly interacting gauge theories.
