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 derives new equations for the multiplicity distribution of produced gluons in deep inelastic scattering on heavy nuclei using a dipole approach and AGK cutting rules, develops a homotopy method to solve them, and provides an analytical solution for large multiplicities to calculate the resulting gluon entropy.
This paper proposes a new dispersive framework for the analytic continuation of hadronic current correlators, deriving subtracted dispersion relations that connect spacelike deep inelastic scattering structure functions to timelike fragmentation functions while introducing a factorized function to quantify crossing obstructions.
This paper presents a perturbative QCD-based energy loss model calibrated on large systems that successfully predicts experimental data in small systems like Ne+Ne and O+O, yet surprisingly forecasts a near-zero high- elliptic flow () due to a geometric decorrelation between hard and soft participant planes inherent to standard experimental measurement methods.
Motivated by color coherence and decoherence effects, this paper proposes a theoretical framework combining vacuum-like evolution and medium-induced radiation to successfully describe the inclusive jet modification factor and its substructure dependence in 0–10% PbPb collisions at as measured by ATLAS.
This paper demonstrates the existence and dynamical stability of current-carrying "kinky vorton" ring solutions within the -symmetric global two-Higgs-doublet model, validating their description via thin string approximations and suggesting a mechanism for their formation in three-dimensional settings through composite domain wall configurations.
Using first-principles lattice simulations with an exact center symmetry induced by a specific imaginary isospin chemical potential, this study demonstrates that QCD with three degenerate dynamical quarks undergoes a first-order deconfinement phase transition and maps its behavior in the mass-isospin chemical potential plane.
This paper demonstrates that a classical, exactly solvable model of the electron proposed by Bialynicki-Birula successfully reproduces the leading non-analytic terms in the small-t expansion of the energy-momentum tensor form factors for a charged particle in QED, while also offering insights into the regularized proton D-term.
This paper introduces a TeV-scale Type-V Seesaw model featuring new fermionic multiplets that generate Majorana neutrino masses via a dimension-9 operator, and it investigates its phenomenological implications by constraining Yukawa couplings through lepton flavor violation limits and establishing 95% CL mass bounds for the new particles using CMS multilepton data.
This paper conducts a comprehensive study of the Type-II see-saw mechanism with a non-degenerate triplet Higgs spectrum, deriving updated 95% CL lower limits on the doubly charged scalar mass that exceed current LHC constraints by 50–230 GeV while identifying unconstrained parameter regions and proposing improved search strategies for the high-luminosity phase.
This paper investigates a cosmological scenario where mini primordial black holes, formed during a stiff fluid domination phase in runaway inflation models, evaporate to reheat the early universe, while also predicting a compound gravitational wave signal, potential dark energy contributions, and the existence of PBH remnants.
