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 implements and analyzes two distinct gauge field flow constructions—gradient flow decoupling and equation-of-motion (EOM) flow—for chiral gauge theories formulated with domain wall fermions on a lattice slab, demonstrating how these methods successfully preserve current conservation and realize anomaly inflow in the presence of background gauge fields.
This paper summarizes recent higher-order computational progress on signal-background interference effects in gluon-fusion Higgs boson production, demonstrating that destructive interference reduces the resonant production rates by approximately 1.6% in the channel and 3% in the mode.
This paper proposes that gauged abelian flavor symmetries can protect the axion from Planck-suppressed operators to solve the strong CP problem while explaining flavor hierarchies, leading to a distinctive plateau-valley gravitational wave spectrum from cosmic string networks that serves as a unique probe complementary to low-energy flavor experiments.
This paper calculates diffractive photoproduction in ultraperipheral lead-lead and proton-lead collisions at the LHC using the GA--FONLL framework to quantify coherent contributions rejected by current neutron-tagged selections and to provide predictions for both inclusive and diffractive cross sections.
Using QCD sum rules with six independent interpolating currents and including nonperturbative condensates up to dimension ten, this study predicts the mass of a compact hidden-charm hexaquark with quark content to be in the range of 3.94–4.41 GeV, providing a theoretical reference for future experimental searches.
This paper proposes a Born-Oppenheimer effective field theory framework for pion transitions involving heavy quarkonium and exotic states with large sizes, deriving universal low-energy functions via a pion-string interaction Lagrangian to calculate and phenomenologically analyze long-distance dominated transition amplitudes where the standard QCD multipole expansion fails.
This paper proposes a novel search strategy for heavy Majorana neutrinos at future muon-proton colliders via lepton-number-violating signals, demonstrating that the facility can achieve significantly superior constraints on neutrino mixing parameters compared to existing LHC bounds for neutrino masses between 200 GeV and 3 TeV.
This paper improves the calculation of bulk viscosity in binary mixtures by deriving a second-order Chapman-Enskog result that captures essential physical features missed by first-order approximations and demonstrates significantly better agreement with Green-Kubo benchmarks.
This paper establishes a non-perturbative light-front framework to define and compute spin-orbit correlation distributions in charmonium and mesons via the parity-odd energy-momentum tensor, revealing that these observables provide rich, non-trivial insights into partonic dynamics even in systems with zero total angular momentum.
Using the Chapman-Enskog method within kinetic theory, this paper derives first- and second-order dissipative relativistic hydrodynamic equations for a multi-component quark-gluon plasma with baryon, electric, and strangeness charges, explicitly calculating the temperature and chemical potential dependence of the resulting diffusion matrix elements and their ratio to shear viscosity.
