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 proposes a theoretical framework that models the vacuum as a meson field to derive the interaction energy and force between two parallel metal plates, drawing an analogy to the nuclear force between nucleons described in Quantum Hadrodynamics.
This paper reports on the development and application of the HF-NRevo framework, which provides a consistent perturbative description of heavy-flavor fragmentation for -wave quarkonia and fully heavy tetraquarks, enabling new investigations into medium effects in heavy-ion collisions and the intrinsic charm content of the proton at future collider facilities.
This paper presents the first lattice-QCD determination of dimension-six four-quark matrix elements for heavy-meson lifetime ratios using gradient flow renormalization on 2+1-flavor domain-wall fermion ensembles, achieving NNLO matching to the scheme and providing precise bag parameters with a full error budget.
This paper demonstrates that the gradient flow combined with short flow-time expansion (GF+SFTX) serves as an effective renormalization procedure for calculating precise bag parameters of four-quark operators relevant to neutral heavy-meson mixing and lifetimes, successfully applying this method to six RBC/UKQCD domain-wall fermion ensembles to obtain results consistent with existing determinations while providing a robust framework for handling power-divergent mixing in future lattice computations.
This paper presents an exactly solvable non-Hermitian Klein-Gordon model where an anomalous inverse-square potential, combined with outgoing boundary conditions, transforms the fall-to-the-center instability into a discrete, log-periodic spectrum of complex energies, thereby establishing a universal framework for quantized dissipation and emergent scale anomalies in relativistic open quantum systems.
This paper reviews recent advances in lattice QCD calculations of hadron structure, specifically for pions, kaons, and nucleons, highlighting how these theoretical developments provide essential insights to inform the scientific agenda of the Electron-Ion Collider.
This paper proposes that implementing early axion relaxation through high-scale confinement within an grand unified theory during inflation generates an early potential that dilutes the axion's energy density, thereby removing the cosmological upper bound on the axion decay constant and allowing it to serve as a viable dark matter candidate for arbitrarily large values across all known axion models.
This paper computes next-to-leading order radiative corrections to the process by incorporating the non-perturbative pion structure via the generalized vector meson dominance model, comparing these results with the naive scalar QED approach to quantify model uncertainties for radiative return experiments at flavor factories.
This paper utilizes the Hidden Gauge Formalism to predict six bottom-strange molecular states, identifying specific mass values for and partners of known charmed mesons and interpreting recent LHCb observations around 6100–6160 MeV as and molecular states.
This paper derives master formulae for tree-level and one-loop scattering amplitudes of arbitrary photon numbers in scalar and spinor QED within non-null background electromagnetic fields using the worldline formalism, thereby extending previous constant-field results to account for realistic laser-plasma dispersive properties through a systematic expansion in the non-null parameter.
