This paper presents the first perturbative QCD predictions for the branching fractions and direct CP asymmetries of the quasi-two-body decays involving various -, -, and -wave resonances, finding results consistent with existing data and predicting vanishing CP asymmetries within the Standard Model.
This paper utilizes gauge/string duality to investigate string breaking in spatial Wilson loops, specifically analyzing the influence of light flavors on the pseudopotential and estimating the spatial string breaking distance for gauge theory across temperatures from 0 to .
This Letter presents a formulation of transition matrix elements for PT-symmetric non-Hermitian Hamiltonians that ensures positivity and perturbative unitarity by utilizing a positive-definite inner product, and demonstrates its application to two-neutrino flavor oscillations and the seesaw mechanism.
This study demonstrates that a hybrid neutron star model incorporating hyperons, deconfined quark matter, and bosonic sexaquark dark matter with a mass of approximately 1900 MeV successfully satisfies all current observational constraints on mass, radius, and tidal deformability.
This paper demonstrates that generalized higher-form symmetries, exemplified by axion electrodynamics, drive a novel self-similar inverse cascade that organizes non-equilibrium turbulent systems into large-scale coherent structures through universal scaling behavior.
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.
