   Neutrino transition dipole moments in light of the KM3NeT event

   Alejandro Muñoz-Ovalle🇪🇸 · Stefan Vogl🇩🇪

   In 2023, KM3NeT observed the highest energy neutrino seen to date. The most probable estimate places the energy of the neutrino at an extreme value of 220 PeV, and energies up to 2.6 EeV are contained in the $90\%$ probability interval. Even though the source of the signal cannot be ascertained with the available data, this observation already opens unique possibilities to test new physics. Here, we study the implications for the transition magnetic dipole portal connecting active and sterile neutrinos. We remain agnostic regarding the origin of the neutrino and focus on local effects. Concretely, we study the impact of efficient active--sterile transitions on the energy degradation experienced by the neutrino along its path to the detector at Earth. We find that the ultra-high-energy neutrino event does not add relevant information for sterile neutrinos with masses less than a TeV. However, the observation becomes important at higher masses and can provide the leading constraint in that regime.

   Flavour Invariants of the N Higgs Doublet Model

   João C. Belas🇵🇹 · João P. Silva🇵🇹

   In this work, a systematic way of analyzing the N Higgs Doublet Models flavor sector will be developed. We introduce a complete set of mixing matrices describing the rotation between certain suitably defined bases, akin to the Cabibbo-Kobayashi-Maskawa matrix, which describes the relation between the up-quark and down-quark mass bases. We point out the crucial importance played by the charged Higgs basis. It is also introduced for the first time a complete set of weak basis transformation invariant traces of flavor matrices for the general N doublets case. This will be important for studies of the renormalization group evolution in terms of relevant physical parameters.

   Investigation of the $l^{-}{l}^{+}\nu \overline{\nu }$ final state at multi-TeV muon colliders through the exclusive decay of ZZ/WW gauge bosons in the Randall-Sundrum model

   Bui Thi Ha Giang🇻🇳 · Dang Van Soa🇻🇳

   An attempt is made to present the effect of the exclusive decay of ZZ/WW gauge bosons at high energy colliders in the Randall-Sundrum (RS) model. In this paper, we investigate the $l^{-}{l}^{+}\nu \overline{\nu }$ final state at muon-TeV colliders through the exclusive decay of ZZ/WW gauge bosons in detail. The result shows that with fixed collision energies, cross-sections for $l^{-}{l}^{+}\nu \overline{\nu }$ production in final state depend strongly on the parameters of the unparticle physics, muon polarization coefficients, parameters on anomalous couplings and also KK-graviton propagators. With the benchmark background $({\Lambda }_U,d_U)$ $=(1$TeV$,1.9)$, the total cross-sections achieve the maximum value when both of muon beams polarize left or right. In case of the different polarization, the cross section increases as the collision energy increases. The numerical evaluation shows that the cross-section for $l^{-}{l}^{+}\nu \overline{\nu }$ final state through the exclusive decay of WW charged bosons is much larger than that of ZZ neutral bosons under the same conditions. With the contribution of new physics in the RS model, the effect is greatly enhanced and the cross-sections for the production of $l^{-}{l}^{+}\nu \overline{\nu }$ final state can be measured in the future muon collisions.

   Dark matter silences Cepheids in the Galactic Center

   Djuna Croon🇬🇧 · Tim Linden🇸🇪 · Jeremy Sakstein🇺🇸

   Upcoming near-infrared facilities (e.g. JWST/NIRCam, ELT/MICADO) will dramatically increase the detectability of galactic center Cepheids despite extreme extinction at optical wavelengths. In this work, we study the impact of dark matter (DM) annihilation on Cepheid stars in the inner parsec of the Milky Way. We show that at captured densities $\rho \sim 10^5$GeV cm${}^{-3}$, blue loop evolution can be suppressed, preventing the formation of low-mass ($3$-$6{\mathrm{M}}_{\odot }$) short-period ($1$-$6$ days) Cepheids. For even slightly higher DM densities, Cepheids are suppressed across their entire mass range. A dearth of such variables could provide indirect evidence for DM heating. Notably, this effect occurs at lower DM densities than required to impact main-sequence stars. Future surveys will thus offer a novel, complementary probe of DM properties in galactic nuclei.

   Dispersion Relations and Pole-Skipping in a Holographic Charmonium Model with Rotating Plasma

   Luiz F. Ferreira🇨🇱

   In this paper, we employ a bottom-up holographic QCD model to investigate the dissociation of charmonium states moving in a rotating medium by calculating their quasinormal modes. We begin by reviewing the holographic quarkonium spectrum at zero temperature. Then, we derive the equations of motion for heavy vector mesons propagating in a rotating plasma, separating the analysis into longitudinal and transverse directions relative to the wave vector. Additionally, we compute the charge diffusion constant in the rotating background and analyze the pole-skipping phenomenon, which emerges in the retarded Green's function. Finally, we investigate the impact of rotation on the spin alignment of the J/psi state in the helicity frame, utilizing the spectral function obtained from the holographic framework.

   Beyond scalar QED radiative corrections: the ${\rho }^{\pm }-{\rho }^0$ width difference, FSR corrections and their impact on $\Delta a_{\mu }^{\mathrm{HVP},\mathrm{LO}}[\tau ]$

   F.V. Flores-Baez🇲🇽 · G. López Castro🇲🇽 · Genaro Toledo🇲🇽

   In a previous paper arXiv:0708.3256 [hep-ph] we have calculated the radiative corrections to $\rho \to \pi \pi$ decays, aiming to estimate the width difference between charged and neutral rho mesons. There, we have used the scalar QED approximation and taken the convection terms to keep the loop contributions finite in the case of charged rho meson decays. Here we compute the radiative corrections by considering the electromagnetic structure of charged mesons and we also include the full Lorentz structure of the electromagnetic vertices. We re-evaluate the width difference of ${\rho }^{\pm }-{\rho }^0$ vector mesons and calculate the structure-dependent contributions to Final State Radiation terms in the $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}$ cross section. Both effects are important inputs for evaluating the isospin breaking corrections in the dominant hadronic vacuum polarization contributions to the muon $g-2$ when using $\tau$ lepton data.

   Inverse magnetic catalysis in the linear sigma model: a beyond mean field approach

   Gabriela Fernández🇲🇽 · Luis A. Hernández🇲🇽 · Ana Mizher🇧🇷

   We explore the restoration of chiral symmetry in the linear sigma model coupled to quarks under the influence of strong magnetic fields and finite temperature, incorporating screening effects through ring diagrams. While previous studies using tree-level thermal masses lead to magnetic catalysis across all temperature ranges, in tension with lattice QCD results, we go beyond this limitation by computing the bosonic masses self-consistently within the lowest Landau level (LLL) approximation. The self-consistent approach modifies the effective potential and allows us to accurately track the thermal evolution of the order parameter. Our results reveal the emergence of a critical end point (CEP) in the $T-|eB|$ phase diagram and, notably, exhibit inverse magnetic catalysis (IMC) behavior: the (pseudo)critical temperature decreases with increasing magnetic field strength. This is in contrast to the magnetic catalysis behavior found when non-self-consistent masses are used. To the best of our knowledge, this is the first time that self-consistent boson masses have been implemented in this context, offering a new framework for exploring the QCD phase diagram using effective models.

   Suppression of scalar perturbations due to a heavy axion

   Kai-Ge Zhang🇨🇳 · Jian-Feng He🇨🇳 · Chengjie Fu🇨🇳 · Zong-Kuan Guo🇨🇳

   A fast-rolling axion can transfer its kinetic energy to gauge fields via the Chern-Simons coupling, leading to copious production of gauge quanta during inflation. The amplified gauge fields act as a source for both scalar and tensor perturbations. In this work, we propose a mechanism for suppressing scalar perturbations while sourcing strong tensor perturbations. We present an implementation of such a mechanism, demonstrating that sourced tensor perturbations are expected to be detected by upcoming next-generation CMB experiments.

   Flavor Imprints on Novel Low Mass Dark Matter

   Ranjeet Kumar🇮🇳 · Hemant Kumar Prajapati🇮🇳 · Rahul Srivastava🇮🇳 · Sushant Yadav🇮🇳

   We present a Majorana scotogenic-like loop framework in which neutrino mass generation and dark matter stability are intrinsically connected to the breaking of the discrete flavor symmetry $A_4$. This breaking leads to the emergence of the scoto-seesaw mechanism and a $Z_2$ symmetry. This naturally explains the solar and atmospheric mass-squared differences, $\Delta m_{sol}^2$ and $\Delta m_{atm}^2$, while simultaneously ensuring dark matter stability. Our model accommodates normal ordering of neutrino masses, with a generalized $\mu$-$\tau$ reflection symmetry shaping the structure of leptonic mixing and a lower limit on the lightest neutrino mass. Moreover, the model provides predictions for the octant of ${\theta }_{23}$ and a strong correlation between $\Delta m_{sol}^2$ and $\Delta m_{atm}^2$. This correlation puts a lower bound on the fermionic DM mass. In contrast, scalar dark matter remains viable over a broad mass spectrum. A notable feature is that the low mass regime ($\sim 15$ GeV onwards) survives owing to the presence of efficient co-annihilation channels, which are typically absent in the Majorana scotogenic scenario. Additionally, the model aligns with current and future limits from lepton flavor violation experiments.

    Perturbative study of NLO chromoelectric correlators in Euclidean space

    Panayiotis Panayiotou🇩🇪

    We report on the perturbative study, at next-to-leading order (NLO), of correlation functions at finite temperature of two chromoelectric fields connected by an adjoint Wilson line in Euclidean space. We find a source of asymmetry in two of the correlators studied. Finally, we compare the results with recent Lattice QCD calculations at high temperatures and show a good agreement between the two.

    Power corrections to the production of a prompt photon in association with a jet in the $N$-jettiness slicing scheme at NLO QCD

    Prem Agarwal🇩🇪 · Kirill Melnikov🇩🇪 · Ivan Pedron🇩🇪

    We compute the next-to-leading-power corrections in the $N$-jettiness variable to the production of a prompt photon and a jet at next-to-leading order in perturbative QCD in the $q\bar{q}$ annihilation channel. We employ the $k_{\perp }$ jet algorithm and assume that the $N$-jettiness value divided by the jet transverse momentum is the smallest parameter in the problem; in particular it should be small compared to the jet radius $R$.

    The top quark in 2025 -- International year of Quantum Science and Technology

    J. A. Aguilar-Saavedra🇪🇸

    Since its discovery at the Tevatron in 1995, the top quark has been extensively studied due to its unique properties. We discuss how the remarkable progress in top-quark physics has opened the possibility of using the top quark as a tool to test quantum mechanics at the energy frontier. After reviewing the motivations for exploring beyond quantum mechanics, we present an example: probing post-quantum correlations at the energy frontier with boosted top quarks.

    First Demonstration that Quark-Gluon Plasma has a Nonzero Resolution Length

    Arjun Srinivasan Kudinoor🇺🇸 · Daniel Pablos🇪🇸 · Krishna Rajagopal🇺🇸

    We report on our investigation in arXiv:2509.08881 of how recent jet substructure measurements constrain the resolution length $L_{\mathrm{res}}$ of the quark-gluon plasma formed in heavy-ion collisions. $L_{\mathrm{res}}$ is defined such that high-energy partons within a jet shower are resolved by the medium if and only if they are separated by a distance greater than $L_{\mathrm{res}}$. Using the Hybrid Model, we reproduce ALICE data on the scaled Soft Drop angle ${\theta }_g$ for $R=0.2$ charged-particle jets and ATLAS data on the Hard Group angle $\Delta R_{12}$ for $R=1$ jets reclustered from skinny $R=0.2$ inclusive subjets. We find that the narrowing of the ${\theta }_g$-distribution in PbPb collisions observed by ALICE and the suppression of $R=1$ jets with multiple skinny subjets in PbPb collisions observed by ATLAS rule out $L_{\mathrm{res}}=\infty$, where each entire parton shower loses energy to the plasma coherently as if it were a single colored object. We then compare Hybrid Model calculations to ATLAS measurements of $R_{\mathrm{AA}}$ of $R=1$ jets reclustered from $R=0.2$ subjets, as a function of the Soft Drop angle $d{R}_{12}$ obtained by grooming all charged-particle tracks associated with each $R=1$ jet. We demonstrate, for the first time, that the ATLAS data is inconsistent with $L_{\mathrm{res}}=0$, where the plasma resolves every splitting in a parton shower. Our results agree best with the data when QGP possesses a finite, nonzero $L_{\mathrm{res}}\sim (1-2)/(\pi T)$.

    Colibri: A new tool for fast-flying PDF fits

    Mark N. Costantini🇬🇧 · Luca Mantani🇪🇸 · James M. Moore🇬🇧 · Valentina Schutze Sanchez🇬🇧 · Maria Ubiali🇬🇧

    We present Colibri, an open-source Python code that provides a general and flexible tool for PDF fits. The code is built so that users can implement their own PDF model, and use the built-in functionalities of Colibri for a fast computation of observables. It grants easy access to experimental data, several error propagation methodologies, including the Hessian method, the Monte Carlo replica method, and an efficient numerical Bayesian sampling algorithm. To demonstrate the capabilities of Colibri, we consider its simplest application: a polynomial PDF parametrisation. We perform closure tests using a full set of DIS data and compare the results of Hessian and Monte Carlo fits with those from a Bayesian fit. We further discuss how the functionalities illustrated in this example can be extended to more complex PDF parametrisations. In particular, the Bayesian framework in Colibri provides a principled approach to model selection and model averaging, making it a valuable tool for benchmarking and combining different PDF parametrisations on solid statistical grounds.

    Foundation models for equation discovery in high energy physics

    Manuel Morales-Alvarado🇮🇹

    Foundation models, large machine learning models trained on broad, multimodal datasets, have been gaining increasing attention in scientific applications due to their strong performance on diverse downstream tasks. Large Language Models (LLMs), a prominent instance of foundation models, have achieved remarkable success in tasks such as text and image generation. In this work, we investigate their potential for equation discovery in high energy physics, focusing on symbolic regression. We apply the LLM-SR methodology both to benchmark problems of equation recovery in lepton angular distributions and to the discovery of functional forms for angular coefficients in electroweak boson production at the Large Hadron Collider, observables of high phenomenological relevance for which no closed-form expressions are known from first principles. Our results demonstrate that LLM-SR can uncover compact, accurate, and interpretable equations across in-domain and out-of-domain kinematic regions, effectively incorporating embedded scientific knowledge and offering a promising new approach to equation discovery in high energy physics.

    Flavor hierarchies with nonminimal irreducible representations

    Hannah Banks🇬🇧 · Graeme Crawford🇬🇧 · Matthew McCullough🇨🇭 · Dave Sutherland🇬🇧

    We propose a new class of flavour models in which the spurion which breaks Standard Model flavour symmetries transforms in a non-minimal representation. Hierarchies in fermion masses, which arise from multiple insertions of this spurion, may be generated in a technically natural, accidental manner, from a handful of untuned $\mathcal{O}(1)$ elements in the UV. This relies explicitly on the non-Abelian nature of the symmetry, distinguishing it from standard Froggatt-Nielsen-like scenarios. The pattern of flavour violating operators at dimension-6 can radically differ from previously considered scenarios, and emphasises the need for a broad flavour programme across all generations.

    Reheating with Thermal Dissipation and Primordial Gravitational Waves

    Kazuma Minami🇯🇵 · Kyohei Mukaida🇯🇵 · Kazunori Nakayama🇯🇵

    In order for an inflationary universe to evolve into a hot universe, a process known as reheating is required. However, the precise mechanism of reheating remains unknown. We show that if the reheating is triggered by thermal dissipation effects, distinctive features appear in the spectrum of primordial gravitational waves. This suggests a possible way to observationally probe the physics of reheating.

    Neural Post-Einsteinian Test of General Relativity with the Third Gravitational-Wave Transient Catalog

    Yiqi Xie🇺🇸 · Gautham Narayan🇺🇸 · Nicolás Yunes🇺🇸

    Gravitational waves (GWs) from compact binaries are excellent probes of gravity in the strong- and dynamical-field regimes. We report a test of general relativity (GR) with the third GW Transient Catalog (GWTC-3) plus a few O4 events using the recently developed neural post-Einsteinian framework, both on individual events and at the population level through hierarchical modeling. We find no significant violation of GR and place a constraint that, for the first time, efficiently covers non-GR theories characterized by not only post-Newtonian deviations but also those beyond under the same theory-agnostic framework.

    Role of universal function of the nuclear proximity potential: A systematic study on the alpha-decay of heavy/super-heavy nuclei and {\alpha}-induced reactions

    S. Mohammadi · R. Gharaei · S. A. Alavi🇮🇷

    The idea of the universal function is fundamental advantage of proximity potential model. We present a systematic study of the role of universal function of the proximity potential model on alpha decay process for 250 ground state to ground state transitions using WKB approximation. In order to realize this goal, five universal functions proposed in the proximity models gp 77, Guo 2013, Ngo 80, Zhang 2013 and Prox. 2010 have been incorporated into the formalism of Prox. 77. The obtained results show that the radial behavior of universal function affects the penetration probability of the {\alpha} particle. The theoretical {\alpha} decay half lives are calculated and compared with the corresponding experimental data. It is shown that the Prox. 77 with Guo 2013 universal function provides the best fit to the available data. The role of the different universal functions in the {\alpha} decay half lives of super heavy nuclei (SHN) with Z from 104 to 118 are also studied. It is shown that the experimental half lives in the super heavy mass region are described well using the Prox. 77 with Zhang 2013 universal function. In this paper, the validity of the original and modified forms of the proximity 77 potential is also examined for complete fusion reactions between {\alpha} particle and 10 different target nuclei. Our results show that the measured {\alpha} induced fusion reaction cross sections can be well reproduced using the Prox. 77 with Zhang 2013 universal function for the reactions involving light and medium nuclei. Whereas, the Prox. 77 with Guo 2013 universal function model demonstrates a reliable agreement with the experimental data at sub-barrier energies for heavier systems.

    Imprints of dynamic fluidization on dilepton production

    Renan Góes-Hirayama🇩🇪 · Zuzana Paulínyová🇸🇰 · Joscha Egger🇩🇪 · Iurii Karpenko🇨🇿 · Hannah Elfner🇩🇪

    We present a newly developed hybrid hadronic transport + hydrodynamics framework geared towards heavy ion collisions at low to intermediate beam energies, and report on the resulting excitation function of dileptons. In this range of energies, it is unclear how to properly initialize the hydrodynamic evolution. Due to the cumulative electromagnetic radiation throughout the collision, dilepton observables are sensitive to the initial condition. In this work, we study how the dilepton ``thermometer'' is affected by employing dynamical initial conditions, in contrast to the traditional fixed-time approach.

    QED vacuum polarization in the Coulomb field of a nucleus: a method of high-order calculation

    Sergey Volkov🇩🇪

    A calculation of the QED vacuum polarization potential in the Coulomb field of a pointlike nucleus was presented in an earlier publication by the author and his collaborators. Corrections up to order ${\alpha }^2(Z\alpha {)}^7$ were evaluated, where $Z$ is the nuclear charge number and $Z\alpha$ is treated as an independent variable. These corrections correspond to two-loop Feynman graphs with proper propagators of fermions in the external field. The calculation employed a reduction to free QED, leading to free QED Feynman graphs with up to eight independent loops. The method of calculation is described here in detail.

    Search for dark matter around intermediate mass black holes with the H.E.S.S. experiment

    Jann Aschersleben🇳🇱 · Dieter Horns🇩🇪 · Emmanuel Moulin🇫🇷 · Manuela Vecchi (for the H.E.S.S. Collaboration)🇳🇱

    Intermediate mass black holes (IMBHs), with masses ranging from a hundred and a million solar masses, are hypothesised to be surrounded by dense regions of dark matter known as dark matter spikes, where the annihilation of dark matter particles could produce detectable gamma rays. The detection of dark matter annihilation around IMBHs therefore offers a promising approach for probing the nature of dark matter. In this work, we search for dark matter annihilation around IMBHs using data from the Galactic Plane Survey, the Extragalactic Survey and a selection of satellite galaxies observed by the H.E.S.S. gamma-ray experiment in Namibia. Since no evidence for a gamma-ray signal from dark matter annihilation around IMBHs has been found, we set upper limits on the velocity-weighted annihilation cross section for dark matter masses between 800 GeV and 100 TeV. Our analysis obtains limits on the velocity-weighted annihilation cross section below the thermal relic cross section for dark matter masses between 10 and 100 TeV.

We discuss the analytical approaches that can be used to obtain qualitative, or in some cases quantitative, information on the $\theta$-dependence of QCD and QCD-like models, discussing their range of validity and comparing their predictions with the numerical results obtained by means of lattice simulations.

    Predictions in modified Glauber model of total charged-particle yields centrality dependence in O+O and Ne+Ne collisions at LHC

    Svetlana Simak · Grigory Feofilov

    In this article we present the results of application of the Monte Carlo modified Glauber model for the predictions of collision centrality dependence of the total charged-particle yields for 16O +16O and 20Ne+20Ne colliding systems at the LHC. Our model differs from the Standard Glauber model by the effective account of the energy losses in successive inelastic nucleon-nucleon collisions. For this purpose, a single model parameter k is defined as a mean fraction of the momentum loss that happens in any binary nucleon collision due to the production of multiple particles. Therefore, the decrease of the nucleon momentum after each inelastic collision leads to a corresponding reduction of the inelastic cross section and the mean multiplicity yield in the subsequent interaction. All these effects are taken into account in the MC model in each of the subsequent inelastic binary interactions. We discuss the purely geometrical effects for these light colliding systems that could be considered useful in future studies of QGP properties in energy density scanning. Predictions in this single parameter model are based on the previous successful analysis of non-linear centrality dependence of charged particle yields observed in Pb+Pb collisions by ALICE at the LHC.

    BaBy Cosmic Tension

    Christophe Ringeval🇧🇪

    We show that the recently released B-mode polarisation data from the South Pole Telescope (SPT) favour a non-vanishing contribution of primordial gravitational waves of inflationary origin which is in tension with the previous BICEP-Keck (BK) measurements. Our analysis uses the third-order slow-roll primordial power spectra, with theoretically motivated priors, on the multifrequency SPT likelihoods complemented by the latest Planck satellite data products. The SPT measurements provide 1.0 bit of information gain on the first slow-roll parameter, which is higher than the 0.9 bit provided by BK even though the SPT sensitivity is five times lower. Moreover, the Bayesian dimensionality on the same parameter exceeds 1.5 for SPT versus 0.3 for BK showing that it is overconstrained by the SPT data. Even if this BB-tension could be the result of a yet to be understood foreground, our findings should motivate for a closer analysis of this unexpected B-modes excess.

    Application of the holographic equations of state for modeling experiments on heavy ion collisions

    A. V. Anufriev🇷🇺 · V. N. Kovalenko🇷🇺

    In this paper, we propose a method for numerical modeling of the nuclear matter properties within the framework of relativistic heavy-ion collisions using a holographic equation of state. Machine learning methods were applied to address the regression and optimization issues during the calibration of the relevant parameters using the LQCD results for quark masses that approximate the physical values. Numerical simulations are performed using the iEBE-MUSIC and vHLLE-SMASH frameworks, which incorporate certain relativistic hydrodynamics solvers. We modify the code by implementing a tabulated holographic equation of state, enabling simulations of quark-gluon plasma evolution with dynamically generated initial conditions via the 3D Monte Carlo Glauber Model and SMASH. Finally, the spectra of produced hadrons are computed using a hybrid iSS+UrQMD and Hadron Sampler+SMASH approaches at the freeze-out stage.12 p
