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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This study employs Bayesian inference with high-accuracy model emulators to analyze RHIC Beam Energy Scan data, thereby providing robust constraints on Quark-Gluon Plasma transport properties, elucidating the sensitivity of experimental observables to model parameters, and generating predictions for -differential observables with estimated systematic uncertainties.
This paper presents a Gaussian Process generative model that integrates theoretical constraints from lattice QCD and hadron resonance gas to produce diverse, smooth crossover equations of state for nuclear matter, thereby establishing a foundation for future Bayesian inference studies using relativistic heavy-ion collision data.
This paper proposes an $SU(9)$ dark grand unification model where a shared asymmetry mechanism and similar gauge coupling running naturally explain the comparable energy densities of dark matter and baryons by predicting GeV-scale dark baryons and a TeV-scale mediator.
This paper utilizes an open quantum system formalism to calculate the inflaton four-point correlation function in axion inflation, demonstrating that the derived parity-odd expansion coefficients in the large limit not only confirm parity violation but also align with recent observational data from galaxy surveys.
This paper investigates the phenomenological implications of a Left-Right Symmetric Model extended with a double type-I seesaw mechanism, demonstrating how fully determined Dirac mass textures can enhance right-handed neutrino contributions to neutrinoless double beta decay and the charged lepton flavor violation process within parameter spaces accessible to current and future experiments.
While shift-symmetric Horndeski and generalized Proca theories struggle to accommodate the phantom-divide crossing suggested by DESI, CMB, and SN Ia data without theoretical pathologies, the authors demonstrate that breaking shift symmetry in Horndeski theories enables a stable model with a scalar potential and Galileon interactions that successfully realizes this transition at low redshifts.
This paper investigates the impact of nuclear effects on muon- and neutrino-tungsten deep inelastic scattering events at the LHC's FASER and FASER experiments, demonstrating that a simultaneous analysis of inclusive and charm-tagged events can test the universality of nuclear effects and reduce uncertainties in parton distribution functions.
This paper proposes a modified hybrid inflation model where a "softened" stiff period driven by the waterfall field resolves the Big Bang Nucleosynthesis constraints on primordial gravitational wave energy density while still producing a characteristic, observable gravitational wave spectrum.
This paper evaluates the impact of intrinsic charm and unflavored meson production on prompt atmospheric lepton fluxes using \texttt{MCEq}, revealing tensions between IceCube's high-energy muon flux measurements and neutrino upper bounds that suggest a need for refined hadronic interaction models and future experimental data to resolve the discrepancies.
This study demonstrates that future electron-positron colliders with integrated luminosities up to 1000 fb⁻¹ can significantly extend the discovery reach for first-generation vector-like leptons, probing masses up to approximately 1440 GeV through optimized multilepton signatures that surpass current hadron collider limits.
