Factorized neural posterior estimation for rapid and reliable inference of parameterized post-Einsteinian deviation parameters in gravitational waves

This paper introduces a factorized neural posterior estimation framework that leverages normalizing flows and hybrid deep learning architectures to achieve millisecond-scale, statistically reliable inference of parameterized post-Einsteinian deviation parameters for gravitational wave tests of general relativity, offering a 9×1049 \times 10^4 speedup over traditional Markov chain Monte Carlo methods.

A Partial Wave Formalism for High-Energy Meson Electroproduction

This paper presents a comprehensive partial-wave formalism for high-energy meson electroproduction that utilizes parity-based symmetries and Regge factorization to separate cross sections and extract production amplitudes directly from spherical harmonic moments, thereby enabling model-independent analysis of unpolarized and polarized data for upcoming experimental programs.

HESS J1507-622: A Plausible Young Galactic Kilonova Remnant

This paper proposes that the unusual TeV gamma-ray source HESS J1507-622 is a young Galactic kilonova remnant, explaining its off-plane location via a natal kick and its observed flux through leptonic inverse-Compton scattering, while predicting unique multi-wavelength signatures like MeV gamma rays from r-process decay for future confirmation.

Imprints of Left-Right Symmetry breaking in Gravitational Wave Spectroscopy: A non-minimal case study

This paper investigates a non-minimal Left-Right symmetric gauge model derived from E6E_6 unification, demonstrating that its rich scalar sector can drive a strong first-order cosmological phase transition at tens of TeVs, producing stochastic gravitational waves detectable by current and future observatories like LISA and DECIGO.

Symmetry-Restoring Counter-terms in Massive Gauge Theories with Non-Anticommuting γ5\gamma_5 via Gauge-Invariant Sector Decomposition

This paper employs the Frölich-Morchio-Strocchi gauge-invariant formalism and cohomological techniques to compute one-loop Slavnov-Taylor identity violations and derive the necessary finite counter-terms for restoring symmetry in a massive Abelian chiral gauge theory regularized via the BMHV scheme, establishing a framework generalizable to non-Abelian cases.

Heavy Dark Baryons at Large NN: Self-Interactions across All Scales

This paper proposes that heavy dark baryons in a moderately large-NN confining SU(N)SU(N) sector can naturally explain the full range of observed dark matter self-interactions across astrophysical scales through van der Waals forces, while simultaneously accounting for the dark matter abundance via a baryon asymmetry and allowing the number of colors NN to be inferred from observational data.

Heavy Dark Baryons as Self-Interacting Dark Matter: A GeV-Scale Coincidence

This paper proposes that heavy dark baryons in a confining SU(N)SU(N) gauge theory with a large number of colors (e.g., N=10N=10) can serve as viable self-interacting dark matter, where attractive multipole forces overcome Pauli repulsion to produce velocity-dependent cross sections consistent with astrophysical observations and GeV-scale masses.
