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 compares prompt photon production modeling in proton-proton collisions at GeV using PYTHIA 8.316 and FeynCalc, finding that quark-gluon Compton scattering dominates the cross section (51.27%) and that photon energy and rapidity distributions follow logarithmic-normal and normal laws, respectively.
This paper derives the intrinsic pressure anisotropy in spherical Proca stars directly from the Einstein-complex-Proca theory, revealing a radially-to-tangentially dominated stress reversal controlled by the local mass-shell threshold that cannot be reproduced by standard phenomenological fluid closures.
This paper calculates the next-to-leading order production of bosons in association with charmed mesons to demonstrate that recent ATLAS data favors a zero strangeness asymmetry in the proton, thereby challenging PDF sets like MSHT20NLO and NNPDF4.0NLO that predict a positive asymmetry.
This paper proposes a method to reconstruct the dark matter equation of state by analyzing gravitational wave signatures from compact binary inspirals, specifically utilizing the -function to isolate dynamical friction effects caused by extended dark matter envelopes surrounding neutron stars.
This paper presents a manifestly gauge-invariant formulation of the Higgs mechanism as a smooth crossover by utilizing gradient-flow regularization to resolve contact-term divergences and enable consistent matching with the standard scheme, as demonstrated at the one-loop level.
This paper presents the most comprehensive global fit of the MSSM electroweakino sector to date, utilizing extensive LEP and LHC Run 2 data to establish stringent mass limits (up to ~1 TeV) and demonstrate that no single scenario can simultaneously explain observed ATLAS and CMS excesses in compressed spectra.
This paper presents precise predictions for the invariant-mass distribution and total cross section of four-top quark production at the Large Hadron Collider by matching next-to-next-to-leading logarithmic (NNLL) threshold resummation to next-to-leading order (NLO) calculations.
This paper proposes an extended minimal Scotogenic model featuring a hidden gauge symmetry and inelastic dark matter scattering to explain the 248 keV event observed by the LZ experiment while simultaneously satisfying constraints from neutrino limits, thermal relic density, and Big Bang Nucleosynthesis.
This paper extends the analysis of gravitationally localized soliton-like solutions to the Einstein-Dirac-Higgs equations by investigating excited and many-fermion states, revealing novel stepwise Higgs field behaviors and significant ADM-to-fermion mass disparities distinct from previously studied two-fermion ground states.
This paper proposes that decays serve as a definitive probe to distinguish between scalar and vector dark-matter mediator scenarios, which were previously fitted to explain the Belle II excess, by predicting distinct enhancement factors of approximately 1.6 and 3.5 respectively compared to Standard Model expectations.
