This paper employs artificial neural networks and stochastic optimization to analyze finite-temperature quantum gravity effects on cosmological parameters, demonstrating that incorporating new temperature-dependent density terms improves the fit to Planck data and suggests a non-negligible role for thermal quantum corrections in cosmological evolution.
This paper calculates the diffuse flux of relic neutrinos boosted by ultra-high-energy cosmic rays, accounting for coherent scattering enhancements to constrain neutrino overdensity using current observatory data and exploring the potential explanation for a recent KM3NeT event.
This paper demonstrates that a cosmologically subdominant but highly collisional dark matter species can accumulate and become dominant within the deep gravitational wells of compact objects like white dwarfs and neutron stars due to gravothermal pile-up.
This paper demonstrates that astrophysical environments surrounding rotating black holes break spacetime symmetries, inducing chaotic orbital dynamics and extending the lifespan of resonant islands in extreme-mass-ratio inspirals, which creates distinct imprints on gravitational-wave signals that challenge current vacuum-based modeling and parameter inference.
This paper demonstrates that a team of large language model (LLM) agents can autonomously generate code to solve complex particle physics data analysis tasks, specifically anomaly detection on the LHC Olympics dataset, achieving performance comparable to human state-of-the-art results.
This paper demonstrates that NLO calculations are essential for achieving reliable predictions of the irreducible gluon-fusion background to vector boson fusion Higgs production, while providing consistent simulation setups to resolve discrepancies among existing event generators.
This paper resolves the apparent conflict between Wigner's theorem and non-invertible symmetries by demonstrating that unitary fusion category symmetries preserve probabilities not through unitary operators on a fixed Hilbert space, but by acting as trace-preserving quantum channels via isometries between distinct Hilbert spaces constructed from twisted sectors.
This paper proposes using topological anomalies in the process to probe the strange-quark electric dipole moment, estimating that current and future experiments like CMD-3, BESIII, Super Tau-Charm, and Belle II could achieve sensitivities ranging from to .
This paper investigates thermal Bhabha scattering within non-Hermitian QED by utilizing Thermofield Dynamics to derive the thermal differential cross section and establish constraints on the axial coupling constant under unbroken PT-symmetry.
This paper reexamines the viability of MeV-scale QCD axions by deriving new constraints from kaon decay measurements, particularly the KTeV data, and concludes that the previously suggested parameter window is effectively excluded even after accounting for theoretical uncertainties.
