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 presents preliminary lattice results on the vector-channel scattering of two pseudoscalar states in an gauge theory with two fundamental Dirac fermions, a candidate model for strongly interacting massive particle dark matter, utilizing Lüscher's formalism to analyze finite-volume energy levels across various fermion masses.
This paper proposes that the global hyperon polarization observed in low-energy heavy-ion collisions can be partially explained (accounting for ~23% of the signal) by a mechanism linking it to long-standing transverse polarization phenomena via the alignment of production and reaction planes driven by directed flow, rather than solely by quark-gluon plasma vorticity.
This study demonstrates that a strong magnetic field in hot hadronic matter induces significant higher-order azimuthal anisotropy in dilepton emission at low invariant masses, characterized by oscillatory flow coefficients () driven by pion Landau-level quantization, thereby establishing dileptons as sensitive probes for constraining magnetic field strengths and hadronic dynamics in heavy-ion collisions.
This paper introduces the quarkyonic QMC (QQMC) model, which combines a dual quarkyonic picture with the quark-meson coupling framework to demonstrate that nuclear interactions significantly enhance the stiffening of the equation of state and trigger an earlier onset of quark saturation in dense matter compared to noninteracting models.
This paper employs the QCD sum rule approach with three distinct interpolating currents to predict the masses and current coupling constants of fully heavy pentaquark candidates containing three charm and two bottom quarks () or three bottom and two charm quarks () with spin-parity .
This paper presents theoretical predictions for exclusive low-invariant-mass pair production in ultraperipheral Pb-Pb collisions at the LHC, incorporating continuum and resonant contributions to calculate cross sections and differential distributions relevant for ALICE, ATLAS, CMS, and LHCb experiments.
The paper demonstrates that vacuum-energy relaxation mechanisms, such as 'yoga' models, suppress the QCD axion's vacuum potential to the point where matter-induced effects dominate, altering its mass-coupling relation and driving it into an observationally excluded regime that renders conventional QCD axions non-viable.
This paper proposes a scotogenic model where the CP-violating decay of a heavy right-handed neutrino simultaneously generates the visible matter asymmetry and a sub-GeV dark matter relic density via freeze-in, successfully reconciling these phenomena with neutrino parameters and flavor observables.
This paper proposes a generalized Georgi-Machacek Model without custodial symmetry to explain recent LHC excesses in vector-boson fusion channels by allowing mass splitting among new Higgs bosons, thereby accommodating observed signals in , , and di-photon production while satisfying experimental constraints.
This paper proposes a left-right unified F-term hybrid inflation model within a extension of the MSSM that successfully dilutes monopoles, generates metastable cosmic strings consistent with PTA gravitational wave observations and recent ACT data, and predicts a low reheating temperature below 34 GeV alongside a PeV-scale SUSY mass spectrum.
