Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes that comparing the electron antineutrino flux inferred from a core-collapse supernova's gamma-ray echo with that detected on Earth can serve as a powerful probe for testing large neutrino emission anisotropies and long-baseline propagation effects, thereby motivating the development of next-generation MeV gamma-ray telescopes.
This paper proposes a model where quark Yukawa couplings arise from Gaussian wave function overlaps in extra dimensions, utilizing machine learning to identify field configurations that naturally reproduce the observed quark mass hierarchies and experimental constraints.
This study proposes that the self-annihilation of a small fraction of dark matter admixed within white dwarfs acts as a hidden energy source, providing a self-consistent explanation for observed discrepancies in their mass-radius relations and unexplained heating.
This study presents the first investigation of shear-induced cavitation in a chemically non-equilibrium, radially expanding Quark-Gluon Plasma, demonstrating that transverse expansion accelerates cavitation onset and establishing a critical shear viscosity threshold that constrains phenomenological models to ensure hydrodynamic validity.
This paper proposes that the isolated 248 keV nuclear recoil event observed by the LUX-ZEPLIN collaboration could be explained by a model featuring inelastic dark matter and flavor-specific non-SM quark Yukawa couplings mediated by a scalar portal, potentially originating from a dimension-6 effective operator at a scale below 10 TeV.
This paper introduces a novel Gaussian Process-based Bayesian framework that robustly reconstructs parton distribution functions from noisy truncated moments, utilizing new tools to correct posterior bias and learn correlation lengths, thereby enabling the application of theoretical first-principles data from lattice QCD to PDF recovery.
This paper demonstrates that QCD thermodynamics in the intermediate-temperature regime can be effectively described by a gas of confining strings with repulsive excluded-volume interactions, where an open-string spectrum characterized by a Hagedorn temperature of approximately 300 MeV and distinct mesonic and baryonic volume parameters successfully reproduces bulk lattice-QCD data above the pseudocritical temperature.
This paper addresses the lack of AI support for the FORM symbolic manipulation language by demonstrating that frontier large language models fail at zero-shot FORM tasks, then introduces a verification-driven fine-tuning pipeline using the FORM binary as an oracle to train a compact 8B-parameter model that outperforms much larger frontier models in code execution and correctness while preserving general reasoning capabilities.
This paper demonstrates that a low-temperature reheating scenario, which dilutes dark matter relic density through delayed inflaton decay, allows dark photon-mediated dark matter to evade current multi-experimental constraints by requiring a significantly smaller kinetic mixing parameter across complex scalar, Dirac, and Majorana fermion models.
This paper proposes that the 248 keV nuclear-recoil candidate observed by LUX-ZEPLIN can be explained as the endothermic hyperfine excitation of a single composite dark hadron within a PQ-augmented dark QCD framework, where a pseudoscalar-to-vector transition naturally produces a localized high-energy recoil peak.
