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 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.
This paper investigates how Coulomb interactions between electrons in -decaying impurities and their solid-state environment affect the energy resolution and visibility required for detecting the cosmic neutrino background, analyzing scenarios ranging from completely suppressed hybridization via dielectric spacers to cases where hybridization is treated perturbatively.
This paper extends a previously developed generally covariant formalism to incorporate the diffusion of conserved charges, while clarifying the apparent distinction between chemical potential and diffusion terms.
This study demonstrates that the carrier-envelope phase and pulse shape of asymmetric electric fields significantly influence electron-positron pair production, with specific configurations capable of enhancing pair density by two to three orders of magnitude through multiphoton dominance and optimized envelope steepness.
This paper investigates conformal quantum mechanics by analyzing perturbative ultraviolet divergences in multi-dimensional -matrices and deriving exact, infinite-series results for the beta function of the inverse square potential in one dimension across both bound and scattering sectors.
