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.

This paper investigates two-body charmed anti-charmed baryonic decays using a topological amplitude approach to decompose various final states, model significant SU(3) flavor symmetry breaking effects, and provide predictions for decay rates while highlighting the substantial uncertainties arising from current limitations in understanding these symmetry-breaking mechanisms.
This paper proposes a novel detection method for MeV-scale solar axion-like particles by analyzing the unique angular and spectral distributions of their decay photons, demonstrating that future space and South Pole terrestrial experiments could probe photon couplings significantly beyond current supernova limits.
This paper demonstrates that even when classical and quantum dynamics are aligned at a specific moment during inflation, their correlation functions diverge exponentially by the end of inflation due to interactions, a difference illustrated through the bispectrum and tensor power spectrum that also clarifies the absence of poles in the scalar bispectrum from finite-time classical evolution.
This paper presents the first global phenomenological fit of inclusive decays to all available experimental data within the Weak Effective Theory, incorporating generic dimension-six New Physics and higher-order corrections, and finds no significant evidence for New Physics while establishing competitive bounds on the relevant Wilson coefficients.
This paper reevaluates three-loop QCD corrections to electroweak vacuum polarization functions to determine contributions to radiative parameters, resulting in improved predictions for the boson mass and the electric charge that are significant for future FCC precision targets.
This paper analyzes the rovibrational spectrum of hydrogen and antihydrogen molecular ions within a low-energy effective theory to demonstrate that these systems offer enhanced sensitivity to Lorentz and CPT violation in the proton sector—scaling as compared to atomic transitions—thereby providing a promising avenue for high-precision tests of fundamental symmetries.
This paper extends a previous analysis of Lorentz and CPT violation in hydrogen and antihydrogen molecular ions by incorporating spin-dependent operators to derive constraints on symmetry-violating couplings from the full hyperfine-Zeeman spectrum under an applied magnetic field.
This paper demonstrates that sustaining a constant electric field in de Sitter space necessitates a tachyonic photon mass, which, when incorporated into an on-shell renormalization scheme, resolves previous infrared divergences by yielding a finite, positive Schwinger current for both charged fermions and scalars.
This paper explicitly calculates the regulator-dependent parameters for three-loop gauge -functions in supersymmetric theories using exponential higher covariant derivative regularization, providing closed-form expressions and demonstrating how finite coupling redefinitions restore the Novikov–Shifman–Vainshtein–Zakharov relation.
This paper investigates how neutron decays into dark baryons affect bulk viscosity in neutron star mergers, finding that while the standard slow decay rate only slightly reduces viscosity, a faster decay rate could significantly enhance it and rapidly dampen merger oscillations.
