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.

The paper argues that simultaneously preserving renormalization group invariance, Ward identities, and parton density sum rules in QCD factorization theorems necessitates that independent factorization and renormalization scales must be equal, with significant implications for phenomenological scale sensitivity, global QCD analyses, and connections to lattice QCD.
This paper utilizes non-observation data from the Pierre Auger Observatory to establish new, flavor-independent 90% confidence-level constraints on the transition magnetic moment between active and heavy sterile neutrinos (1–100 TeV), effectively extending existing bounds into previously unexplored parameter space by distinguishing enhanced interaction cross sections from flux variations.
This paper evaluates the feasibility of detecting Odderon exchange via high-energy neutral-kaon regeneration at the LHC by analyzing both coherent-forward and non-forward diffractive processes, ultimately identifying significant experimental challenges such as primary contamination and competing electromagnetic or Regge backgrounds that necessitate specific mitigation strategies.
This paper demonstrates that multi-TeV muon colliders, specifically at 3 TeV and 10 TeV energies, can achieve high-precision measurements of the trilinear Higgs self-coupling modifier in Higgs boson pair production via vector boson fusion, utilizing advanced machine learning techniques to reach a few-percent precision at 10 TeV that significantly surpasses projections for the High-Luminosity LHC.
This paper demonstrates that the Babu-Nandi-Tavartkiladze (BNT) model, which generates neutrino masses via dimension-7 tree-level and dimension-5 one-loop operators, can successfully accommodate thermal leptogenesis at the TeV scale through resonant enhancement in the quasi-degenerate regime of vector-like fermion triplets, thereby reconciling successful baryogenesis with the model's testability at colliders.
This paper proposes a chiral axion model where the QCD axion emerges as a phase of complex scalars breaking a gauged symmetry, thereby protecting axion quality and establishing a minimal coupling to Standard Model fermions that enhances the model's testability.
This paper derives simple, necessary and sufficient inequalities that ensure nonlinear causality in viscous anisotropic hydrodynamics by analyzing characteristic velocities, thereby establishing the theory's regime of validity for describing the early-time dynamics of relativistic heavy-ion collisions.
This paper reviews recent theoretical advancements in predicting the QCD critical point, focusing on the equation of state, the maximum entropy freeze-out framework for linking hydrodynamic fluctuations to hadronic cumulants, and the dynamical evolution of critical fluctuations.
Using a chiral SU(3) model and the Chapman-Enskog expansion, this study calculates the diffusion and shear viscosity coefficients of hot isospin asymmetric strange hadronic matter, revealing that finite strangeness significantly enhances shear viscosity while isospin asymmetry strongly influences diffusion coefficients but has only a marginal effect on shear viscosity.
Using the Functional Renormalization Group with a hydrodynamical algorithm, this study investigates the (2+1)-dimensional Gross-Neveu-Yukawa model at finite temperature, density, and magnetic field, revealing that strong magnetic fields induce magnetic catalysis and dimensional reduction while weak fields at high chemical potential produce de Haas–van Alphen oscillations and multiple first-order phase transitions alongside a shifting critical endpoint.
