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 investigates intrajet azimuthal anisotropies in high-energy proton-proton collisions by comparing LHC data with PYTHIA soft QCD model predictions across different jet axis definitions, finding that the QCD-scheme color reconnection tune best reproduces the observed collective signatures and offers new insights into nonperturbative QCD dynamics.
This paper proposes that exothermic inelastic dark matter with strongly velocity-dependent scattering, mediated by vector and scalar fields with opposite-sign contributions, explains the observed mass-dependent deficit of dark matter in the central regions of nearby galaxies by suppressing -wave conversion at low velocities while enabling -wave down-scattering at higher velocities to lower central densities.
This paper examines chiral anomalies in baryon and lepton number currents within a GUT-inspired gauge-Higgs unification model in Randall-Sundrum warped space, expressing the total anomalies from all Kaluza-Klein modes in terms of gauge-boson wave functions at the UV and IR branes and identifying a specific anomaly term in the 5D baryon number current proportional to the difference between and topological terms.
This paper presents a background-level observational test of a thermogravity theory where cosmic acceleration arises from energy non-conservation rather than a cosmological constant, finding that while a model restricting non-conservation to cold dark matter improves the fit to distance data compared to CDM, it exacerbates the Hubble tension by lowering the inferred value of .
This paper investigates lepton flavor universality in processes within the SSM framework, demonstrating that while the model cannot fully match experimental data, specific parameter combinations yield improved numerical results over the Standard Model.
This paper reviews the current status of quark-flavour physics and outlines theoretical prospects for benchmark B-meson decay processes, emphasizing their critical role in testing the Standard Model and searching for New Physics at upcoming high-precision experiments like the HL-LHC, Belle II, and FCC-ee.
This paper introduces a novel Monte Carlo sampling method for first-order QED processes in laser and pulsar plasmas that replaces traditional numerical tabulation and root-finding with closed-form Padé approximants, enabling efficient and accurate event generation directly within radiative particle-in-cell codes.
This paper introduces the "Hidden Region Finder" algorithm, which systematically identifies missing "hidden regions" in the asymptotic expansions of Minkowski-space Feynman integrals by linking them to pinch singularities and Landau conditions, revealing that these regions consistently arise from wide-angle configurations with multiple hard-scattering subdiagrams.
This paper investigates the thermodynamic properties and deconfinement phase transition of a hot and dense QCD system within a finite-volume non-extensive Tsallis framework, revealing that the Tsallis parameter significantly influences the transition point and thermodynamic quantities like energy density and pressure.
This paper demonstrates that heavy fields during quasi-single-field inflation can significantly enhance primordial black hole formation by generating non-Gaussianities, where the trispectrum contribution is often comparable to or even dominates the bispectrum effect, thereby establishing PBH abundance as a novel probe for cosmological collider physics.
