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 applies the spin-spinor formalism to calculate amplitudes for specific massive particle processes, visualizes spin flow using charts to analyze symmetries, and investigates the massless limit through the concept of Little Group Contraction.
This paper calculates the first five leading-twist moments of the light-cone distribution amplitude using QCD sum rules within background field theory, employs these results to construct distribution amplitude models and compute transition form factors, and subsequently analyzes the phenomenological implications for the semileptonic decay , including its branching ratios and angular observables.
Motivated by Grand Unification, this study demonstrates that in an SU(3) gauge theory, a small non-vanishing bias parameter () can suppress the over-abundance of magnetic monopoles by controlling the decay of domain walls, while simultaneously predicting a stochastic gravitational wave background and the potential formation of magnetically charged black holes.
This paper demonstrates that while host-galaxy and Milky Way magnetic fields have only a mild impact on axion-like particle constraints derived from GRB 221009A, the properties of the intergalactic magnetic field constitute the dominant astrophysical uncertainty, significantly altering exclusion limits and introducing oscillatory features in the ALP mass-coupling plane.
This paper explores the synergy between observable gravitational waves from first-order phase transitions driven by a leptophilic Higgs doublet and distinct particle physics signatures, such as same-sign dilepton events and charged lepton flavor violation, within the minimal low-scale linear seesaw model to probe neutrino properties.
This paper derives thermodynamic currents for a perfect fluid of massive spin-1 particles obeying Bose-Einstein statistics using the Wigner-function approach, demonstrating that the resulting spin-extended hydrodynamic framework provides a unified, causal, and stable description of relativistic spin hydrodynamics that is independent of both particle statistics and spin representation.
This paper systematically investigates the pion-emission decays of excited hidden-charm pentaquark molecules composed of and radially excited states into known ground-state molecules, revealing that decay widths are highly sensitive to spin structures and coupled-channel interferences to provide decisive experimental signatures for future verification at LHCb and PANDA.
This paper proposes a model in Einstein-Gauss-Bonnet gravity where a complex scalar field with a Mexican hat potential undergoes a phase transition during inflation, generating strong small-scale primordial inhomogeneities and a gravitational wave background consistent with NANOGrav observations while avoiding large-scale isocurvature perturbations.
This paper employs an effective Lagrangian approach to successfully reproduce the production cross sections of known high-orbital kaon excited states in reactions and predicts that other such states exhibit sizable, forward-peaked cross sections, indicating their strong potential for future experimental observation.
This paper resolves the apparent contradiction between free-quark-like fluctuations of conserved charges and confined mesonic correlators above the chiral crossover by demonstrating that while mesonic propagation remains string-bound, conserved quark number densities effectively bypass confinement through quark interchanges between overlapping color-singlet clusters, a phenomenon analogous to quark-hadron duality.
