   $B\to \rho l\bar{\nu }$ and $\omega l\bar{\nu }$ in and beyond the Standard Model: Improved predictions and $|V_{ub}|$

   Florian U. Bernlochner🇩🇪 · Markus T. Prim🇩🇪 · Dean J. Robinson🇺🇸

   We revisit the experimental and theoretical status of $B\to \rho l\bar{\nu }$ and $B\to \omega l\bar{\nu }$ decays. We perform a combined fit of averaged spectra from Belle and Babar measurements with prior light cone sum rule calculations, in order to obtain more precise predictions over the full $q^2$ range. The extracted values of $|V_{ub}|$ from these combined fits exhibit smaller uncertainty compared to previous extractions from $B\to \rho l\bar{\nu }$ and $B\to \omega l\bar{\nu }$ decays and the central values are found to be smaller than values extracted from $B\to \pi l\nu$ or inclusive measurements. We use our fit results to obtain more precise predictions in and beyond the Standard Model for the lepton universality ratios $R(\rho )$ and $R(\omega )$, as well as several angular observables that are sensitive to the full $q^2$ distribution, such as the longitudinal polarization of the vector meson, the $\tau$ polarization, and its forward-backward asymmetry.

   Roberto Franceschini🇮🇹 · Mario Greco🇮🇹

   We describe recent work on the physics of the Higgs boson at future muon colliders. Starting from the low energy muon collider at the Higgs boson pole we extend our discussion to the multi-TeV muon collider and outline the physics case for such machines about the properties of the Higgs boson and physics beyond the Standard Model that can be possibly discovered.

   Three-loop corrections to the muon and heavy quark decay rates

   Michał Czakon🇩🇪 · Andrzej Czarnecki🇨🇦 · Matthew Dowling🇨🇦

   Recently, $O({\alpha }^3)$ corrections to the muon decay rate and $O({\alpha }_s^3)$ to heavy quark decays have been determined by Fael, Schönwald, and Steinhauser. This is the first such perturbative improvement of these important quantities in more than two decades. We reveal and explain a symmetry pattern in these new corrections, and confirm the most technically difficult parts of their evaluation.

   Combined analysis of neutrino decoherence at reactor experiments

   André de Gouvêa🇺🇸 · Valentina De Romeri🇪🇸 · Christoph A. Ternes🇮🇹

   Reactor experiments are well suited to probe the possible loss of coherence of neutrino oscillations due to wave-packets separation. We combine data from the short-baseline experiments Daya Bay and the Reactor Experiment for Neutrino Oscillation (RENO) and from the long baseline reactor experiment KamLAND to obtain the best current limit on the reactor antineutrino wave-packet width, $\sigma >2.1\times 10^{-4}$ nm at 90% CL. We also find that the determination of standard oscillation parameters is robust, i.e., it is mostly insensitive to the presence of hypothetical decoherence effects once one combines the results of the different reactor neutrino experiments.

   QCD phase diagram in a magnetized medium from the chiral symmetry perspective: The linear sigma model with quarks and the Nambu--Jona-Lasinio model effective descriptions

   Alejandro Ayala🇲🇽 · Luis A. Hernández🇿🇦 · Marcelo Loewe🇨🇱 · Cristian Villavicencio🇨🇱

   We review the main features of the QCD phase diagram description, at finite temperature, baryon density and in the presence of a magnetic field, from the point of view of effective models, whose main ingredient is chiral symmetry. We concentrate our attention on two of these models: The linear sigma model with quarks and the Nambu--Jona-Lasinio model. We show that a main ingredient to understand the characteristics of the phase transitions is the inclusion of plasma screening effects that capture the physics of collective, long-wave modes, and thus describe a prime property of plasmas near transition lines, namely, long distance correlations. Inclusion of plasma screening makes possible to understand the inverse magnetic catalysis phenomenon even without the need to consider magnetic field-dependent coupling constants. Screening is also responsible for the emergence of a critical end point in the phase diagram even for small magnetic field strengths. Although versatile, the NJL model is also a more limited approach since, being a non-renormalizable model, a clear separation between pure vacuum and medium effects is not always possible. The model cannot describe inverse magnetic catalysis unless a magnetic field dependent coupling is included. The location of the critical end point strongly depends on the choice of the type of interaction and on the magnetic field dependence of the corresponding coupling. Overall, both models provide sensible tools to explore the properties of magnetized, strongly interacting matter. However, a cross talk among them as well as a consistent physical approach to determine the model parameters is much needed.

   Investigating high energy proton proton collisions with a multi-phase transport model approach based on PYTHIA8 initial conditions

   Liang Zheng🇨🇳 · Guang-Hui Zhang🇨🇳 · Yun-Fan Liu🇨🇳 · Zi-Wei Lin🇺🇸 · Qi-Ye Shou🇨🇳 · Zhong-Bao Yin🇨🇳

   The striking resemblance of high multiplicity proton-proton (pp) collisions at the LHC to heavy ion collisions challenges our conventional wisdom on the formation of the Quark-Gluon Plasma (QGP). A consistent explanation of the collectivity phenomena in pp will help us to understand the mechanism that leads to the QGP-like signals in small systems. In this study, we introduce a transport model approach connecting the initial conditions provided by PYTHIA8 with subsequent AMPT rescatterings to study the collective behavior in high energy pp collisions. The multiplicity dependence of light hadron productions from this model is in reasonable agreement with the pp $\sqrt{s}=13$ TeV experimental data. It is found in the comparisons that both the partonic and hadronic final state interactions are important for the generation of the radial flow feature of the pp transverse momentum spectra. The study also shows that the long range two particle azimuthal correlation in high multiplicity pp events is sensitive to the proton sub-nucleon spatial fluctuations.

   Ambiguities in the hadro-chemical freeze-out of Au+Au collisions at SIS18 energies and how to resolve them

   Anton Motornenko🇩🇪 · Jan Steinheimer🇩🇪 · Volodymyr Vovchenko🇺🇸 · Reinhard Stock🇩🇪 · Horst Stoecker🇩🇪

   The thermal fit to preliminary HADES data of Au+Au collisions at $\sqrt{s_{{}_{NN}}}=2.4$ GeV shows two degenerate solutions at $T\approx 50$ MeV and $T\approx 70$ MeV. The analysis of the same particle yields in a transport simulation of the UrQMD model yields the same features, i.e. two distinct temperatures for the chemical freeze-out. While both solutions yield the same number of hadrons after resonance decays, the feeddown contribution is very different for both cases. This highlights that two systems with different chemical composition can yield the same multiplicities after resonance decays. The nature of these two minima is further investigated by studying the time-dependent particle yields and extracted thermodynamic properties of the UrQMD model. It is confirmed, that the evolution of the high temperature solution resembles cooling and expansion of a hot and dense fireball. The low temperature solution displays an unphysical evolution: heating and compression of matter with a decrease of entropy. These results imply that the thermal model analysis of systems produced in low energy nuclear collisions is ambiguous but can be interpreted by taking also the time evolution and resonance contributions into account.

   Meson Spectra using Nikiforov-Uvarov Method

   Hesham Mansour🇪🇬 · Ahmed Gamal🇪🇬

   There are many phenomenological potentials using different techniques to describe the spectroscopy of the quarkonium systems like charmonium, bottomonium, Bc meson systems. In the present work, we choose a phenomenological potential (linear, Yukawa, and harmonic potentials) in the framework of the nonrelativistic Schrodinger equation with relativistic corrections using the Nikiforov-Uvarov (NU) method. We obtained the eigenfunction and eigenvalue comparing the results with the available experimental data. The results are in good agreement with the available experimental data.

   Implications of Feebly Interacting Dark Sector on Neutron Star Properties and Constraints from GW170817

   Debashree Sen🇮🇳 · Atanu Guha🇮🇳

   We investigate the effect of feeble interaction of dark matter (DM) with hadronic matter on the equation of state (EoS) and structural properties of neutron stars (NSs) in static conditions. For the purpose we adopt the effective chiral model for the hadronic sector and for the first time in the context of possible existence of DM inside NSs, we introduce DM-SM interaction through light new physics mediator. Moreover, the mass of DM fermion, the mediator and the coupling are adopted from the self-interaction constraint from Bullet cluster and from present day relic abundance. Within the considered framework, the work highlights the underlying stiffening of EoS in presence of DM fermion of mass of the order of a few GeV compared to the no-DM scenario. Consequently, the maximum gravitational mass of NS is obtained consistent with the bounds from the most massive pulsars which were not satisfied with the hadronic matter EoS alone. The estimates of radius and tidal deformability of 1.4 $M_{\odot }$ NS and the tidal deformabilities of the individual components of the binary neutron stars (BNS) associated with GW170817 are all in good agreement with the individual constraints obtained from GW170817 observation of BNS merger.

    Precision Gamma-Ray Constraints for Sub-GeV Dark Matter Models

    Adam Coogan🇳🇱 · Logan Morrison🇺🇸 · Stefano Profumo🇺🇸

    The indirect detection of dark matter particles with mass below the GeV scale has recently received significant attention. Future space-borne gamma-ray telescopes, including All-Sky-ASTROGAM, AMEGO, and GECCO, will probe the MeV gamma-ray sky with unprecedented precision, offering an exciting test of particle dark matter in the MeV-GeV mass range. While it is typically assumed that dark matter annihilates into only one Standard Model final state, this is not the case for realistic dark matter models. In this work we analyze existing indirect detection constraints and the discovery reach of future detectors for the well-motivated Higgs and vector-portal models using our publicly-available code Hazma. In particular, we show how to leverage chiral perturbation theory to compute the dark matter self-annihilation cross sections into final states containing mesons, the strongly-interacting Standard Model dynamical degrees of freedom below the GeV scale. We find that future telescopes could probe dark matter self-annihilation cross sections orders of magnitude smaller than those presently constrained by cosmic microwave background, gamma-ray and terrestrial observations.

    Analysis of the interpolating currents of baryons: anomalous dimension

    Zhen-Xing Zhao🇨🇳 · Yu-Ji Shi🇩🇪 · Zhi-Peng Xing🇨🇳

    The anomalous dimensions for the interpolating currents of baryons are indispensable inputs in a serious QCD analysis of baryon. However, the results in the literature are vague. In view of this, in this work, we investigate the one-loop anomalous dimensions for some interpolating currents such as those of ${\Lambda }_Q$ and proton. Under the requirement of precise testing the Standard Model, this study is essential and significant for the QCD analysis in the future.

    $(g-2{)}_{\mu }$ anomaly within the left-right symmetric model

    O. M. Boyarkin🇧🇾 · G. G. Boyarkina🇧🇾 · V. V. Makhnach🇧🇾

    The muon anomalous magnetic moment is discussed within the model based on the $SU(2{)}_L\times SU(2{)}_R\times U(1{)}_{B-L}$-gauge group. The contributions of the neutrinos having the dipole magnetic moment (DMM) are calculated. The cases of the Majorana and Dirac neutrino are considered. It is shown that to account for the $(g-2{)}_{\mu }$ anomaly DMMs connected with heavy neutrinos should be on the order of $\text{mbox}few\times 10^{-8}{\mu }_B$, that is at variance with the theoretically predicted values.

    Cutting rules on a cylinder: a bottom-up approach to quantum kinetic theory for the early universe

    Tomáš Blažek🇸🇰 · Peter Maták🇸🇰

    Nonequilibrium quantum field theory is often used to derive an approximation for the evolution of number densities and asymmetries in astroparticle models when a more precise treatment of quantum thermal effects is required. This work presents an alternative framework using the zero-temperature quantum field theory, $S$-matrix unitarity, and classical Boltzmann equation as starting points leading to a set of rules for calculations of thermal corrections to reaction rates. Statistical factors due to on-shell intermediate states are obtained from the cuts of forward diagrams with multiple spectator lines. It turns out that it is equivalent to cutting closed diagrams on a cylindrical surface.

    Next-to-leading non-global logarithms in QCD

    Andrea Banfi🇬🇧 · Frédéric A. Dreyer🇬🇧 · Pier Francesco Monni🇨🇭

    Non-global logarithms arise from the sensitivity of collider observables to soft radiation in limited angular regions of phase space. Their resummation to next-to-leading logarithmic (NLL) order has been a long standing problem and its solution is relevant in the context of precision all-order calculations in a wide variety of collider processes and observables. In this article, we consider observables sensitive only to soft radiation, characterised by the absence of Sudakov double logarithms, and we derive a set of integro-differential equations that describes the resummation of NLL soft corrections in the planar, large-$N_c$ limit. The resulting set of evolution equations is derived in dimensional regularisation and we additionally provide a formulation that is manifestly finite in four space-time dimensions. The latter is suitable for a numerical integration and can be generalised to treat other infrared-safe observables sensitive solely to soft wide-angle radiation. We use the developed formalism to carry out a fixed-order calculation to $\mathcal{O}({\alpha }_s^2)$ in full colour for both the transverse energy and energy distribution in the interjet region between two cone jets in $e^{+}{e}^{-}$ collisions. We find that the expansion of the resummed cross section correctly reproduces the logarithmic structure of the full QCD result.

    Addendum to: Combined Constraints on First Generation Leptoquarks

    Andreas Crivellin · Luc Schnell

    In this addendum to arXiv:2101.07811 we discuss the implications of the recent CMS analysis of lepton flavour universality violation in non-resonant di-lepton pairs for first generation leptoquarks. As CMS finds more electron events than expected from background, this analysis prefers the LQ representations ${\tilde{S}}_1,S_2,S_3,{\tilde{V}}_1,V_2({\kappa }_2^{RL}\ne 0)$ and $V_3$ which lead to constructive interference with the SM. In principle the excess could also be (partially) explained by the representations ${\tilde{S}}_2,V_1({\kappa }_1^R\ne 0),V_2({\kappa }_2^{LR}\ne 0),{\tilde{V}}_2$ which are interfering destructively, as this would still lead to the right effect in bins with high invariant mass where the new physics contribution dominates. However, in these cases large couplings would be required which are excluded by other observables. The representations $S_1,V_1({\kappa }_1^L\ne 0)$ cannot improve the fit to the CMS data compared to the SM.

    Searching for lepton portal dark matter with colliders and gravitational waves

    Jia Liu🇨🇳 · Xiao-Ping Wang🇨🇳 · Ke-Pan Xie🇰🇷

    We study the lepton portal dark matter (DM) model in which the relic abundance is determined by the portal coupling among the Majorana fermion DM candidate $\chi$, the singlet charged scalar mediator $S^{\pm }$ and the Standard Model (SM) right-handed lepton. The direct and indirect searches are not sensitive to this model. This article studies the lepton portal coupling as well as the scalar portal coupling (between $S^{\pm }$ and SM Higgs boson), as the latter is generally allowed in the Lagrangian. The inclusion of scalar portal coupling not only significantly enhances the LHC reach via the $gg\to h^{\ast }\to S^{+}{S}^{-}$ process, but also provides a few novel signal channels, such as the exotic decays and coupling deviations of the Higgs boson, offering new opportunities to probe the model. In addition, we also study the Drell-Yan production of $S^{+}{S}^{-}$ at future lepton colliders, and find out that the scenario where one $S^{\pm }$ is off-shell can be used to measure the lepton portal coupling directly. In particular, we are interested in the possibility that the scalar potential triggers a first-order phase transition and hence provides the stochastic gravitational wave (GW) signals. In this case, the terrestrial collider experiments and space-based GW detectors serve as complementary approaches to probe the model.

    Trapped electrons and ions as particle detectors

    Daniel Carney🇺🇸 · Hartmut Häffner🇺🇸 · David C. Moore🇺🇸 · Jacob M. Taylor🇺🇸

    Electrons and ions trapped with electromagnetic fields have long served as important high-precision metrological instruments, and more recently have also been proposed as a platform for quantum information processing. Here we point out that these systems can also be used as highly sensitive detectors of passing charged particles, due to the combination of their extreme charge-to-mass ratio and low-noise quantum readout and control. In particular, these systems can be used to detect energy depositions many orders of magnitude below typical ionization scales. As illustrations, we suggest some applications in particle physics. We outline a non-destructive time-of-flight measurement capable of sub-eV energy resolution for slowly moving, collimated particles. We also show that current devices can be used to provide competitive sensitivity to models where ambient dark matter particles carry small electric millicharges $\ll e$. Our calculations may also be useful in the characterization of noise in quantum computers coming from backgrounds of charged particles.

    Non-extensive Boltzmann Transport Equation: the Relaxation Time Approximation and Beyond

    Trambak Bhattacharyya🇷🇺

    We derive approximate iterative analytical solutions of the non-extensive Boltzmann transport equation in the relaxation time approximation. The approximate solutions almost overlap with the exact solution for a considerably wide range of the parameter values found in describing particle spectra originated in high-energy collisions. We also discuss the Landau kinetic approximation of the non-extensive Boltzmann transport equation and the emergence of the non-extensive Fokker-Planck equation, and use it to estimate the drag and diffusion coefficients of highly energetic light quarks passing through a gluonic plasma.

    Interacting quintessence in light of Generalized Uncertainty Principle: Cosmological perturbations and dynamics

    Andronikos Paliathanasis🇿🇦 · Genly Leon🇨🇱 · Wompherdeiki Khyllep🇮🇳 · Jibitesh Dutta🇮🇳 · Supriya Pan🇮🇳

    We consider a cosmological scenario endowed with an interaction between the universe's dark components $-$ dark matter and dark energy. Specifically, we assume the dark matter component to be a pressure-less fluid, while the dark energy component is a quintessence scalar field with Lagrangian function modified by the quadratic Generalized Uncertainty Principle. The latter modification introduces new higher-order terms of fourth-derivative due to quantum corrections in the scalar field's equation of motion. Then we investigate asymptotic dynamics and general behaviour of solutions of the field equations for some interacting models of special interests in the literature. At the background level, the present interacting model exhibits the matter-dominated and de Sitter solutions which are absent in the corresponding quintessence model. Furthermore, to boost the background analysis, we study cosmological linear perturbations in the Newtonian gauge where we show how perturbations are modified by quantum corrected terms from the quadratic Generalized Uncertainty Principle. Depending on the coupling parameters, scalar perturbations show a wide range of behavior.

    Does our universe conform with the existence of a universal maximum energy-density ${\rho }_{max}^{uni}$ ?

    A.A. Hujeirat🇩🇪

    Recent astronomical observations of high redshift quasars, dark matter-dominated galaxies, mergers of neutron stars, glitch phenomena in pulsars, cosmic microwave background and experimental data from hadronic colliders do not rule out, but they even support the hypothesis that the energy-density in our universe most likely is upper-limited by ${\rho }_{max}^{uni},$ which is predicted to lie between $2$ to $3$ the nuclear density ${\rho }_0.$ Quantum fluids in the cores of massive NSs with $\rho \approx {\rho }_{max}^{uni}$ reach the maximum compressibility state, where they become insensitive to further compression by the embedding spacetime and undergo a phase transition into the purely incompressible gluon-quark superfluid state. A direct correspondence between the positive energy stored in the embedding spacetime and the degree of compressibility and superfluidity of the trapped matter is proposed. In this paper relevant observation signatures that support the maximum density hypothesis are reviewed, a possible origin of ${\rho }_{max}^{uni}$ is proposed and finally the consequences of this scenario on the spacetime's topology of the universe as well as on the mechanisms underlying the growth rate and power of the high redshift QSOs are discussed.

    Gluon Parton Distribution of the Pion from Lattice QCD

    Zhouyou Fan🇺🇸 · Huey-Wen Lin🇺🇸

    We present the first determination of the $x$-dependent pion gluon distribution from lattice QCD using the pseudo-PDF approach. We use lattice ensembles with 2+1+1 flavors of highly improved staggered quarks (HISQ), generated by MILC Collaboration, at two lattice spacings $a\approx 0.12$ and 0.15~fm and three pion masses $M_{\pi }\approx 220$, 310 and 690 MeV. We use clover fermions for the valence action and momentum smearing to achieve pion boost momentum up to 2.29 GeV. We find that the dependence of the pion gluon parton distribution on lattice spacing and pion mass is mild. We compare our results from the lightest pion mass ensemble with the determination by JAM and xFitter global fits.

    Current and Future constraints on single-field $\alpha$-Attractor model

    Guadalupe Cañas-Herrera🇳🇱 · Fabrizio Renzi🇳🇱

    We study here the observational constraints on single-field inflationary models achievable with the next generation of CMB experiments. We particularly focus on a Stage-IV like experiment and forecasts its constraints on inflationary parameters in the context of $\alpha$-attractor inflation comprising a large class of single-field models. To tailor our forecasts we use as a fiducial model the results obtained with current CMB and LSS data, assuming the $\alpha$-model a priori. We found that current CMB data are able to place a tight bound on the ratio of the tensor-to-scalar ratio with the alpha parameter $r/\alpha =3.87_{-0.94}^{+0.78}\cdot 10^{-3}$ and on the running of the scalar index ${\alpha }_S=-6.4_{-1.3}^{+1.6}\cdot 10^{-4}$ with a value of the scalar index consistent with current constraints. In the optimistic scenario of detection of primordial gravitational waves in the CMB B-mode polarization power spectra, we found that CMB-S4 will be able to achieve a $15\%$ bound on the value of the parameter $\alpha =1.01_{-0.18}^{+0.14}$. This bound clearly show the ability of CMB-S4 to constrain not only the energy scale of inflation but also the shape of its potential. Enlarging the baseline model to also include the neutrino sector merely reduce the accuracy of $5\%$ leading to $\alpha =1.07_{-0.23}^{+0.18}$ so that our main conclusions are still valid.

    AdS Swampland Conjectures and Light Fermions

    Eduardo Gonzalo🇪🇸 · Luis E. Ibáñez🇪🇸 · Irene Valenzuela🇺🇸

    We consider constraints on $D$-dimensional theories in $M_D$, $d{S}_D$ and $Ad{S}_D$ backgrounds in the light of AdS swampland conjectures as applied to their compactification in a circle. In particular we consider the non-SUSY AdS instability conjecture and the AdS distance conjecture. For $M_D$ and $d{S}_D$ vacua the results may be summarized by a light fermion conjecture which states that in theories with ${\Lambda }_D\ge 0$ and a positive first non-vanishing supertrace $(-1{)}^{k+1}\text{Str}{M}^{2k}>0$, a surplus of light fermions with mass $m_f\lesssim {\Lambda }_D^{1/D}$ must be present. On the contrary, the cases of $M_D$ and $Ad{S}_D$ can be made consistent with the mild but not the strong version of the AdS Distance conjecture, since the KK tower in the lower $d$-dim theory will scale as $m\lesssim {\Lambda }_d^{\alpha }$ with $\alpha =1/d$. The above constraints also suggest that the Standard Model of particle physics would be inconsistent in Minkowski space but consistent in dS if the lightest neutrino is Dirac and lighter than the cosmological constant scale.

For integrands less than 5 dimensions, it usually takes less than 10 minutes to finish the evaluation of $10^3$ integrations on one Tesla v100 card. The performance scales linearly with the increasing of the GPUs.
