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 paper investigates a renormalizable SU(5) grand unified theory with a 45-dimensional Higgs field and a DFSZ axion sector, demonstrating how Georgi--Jarlskog flavor constraints and one-loop gauge coupling unification establish a direct correlation between viable proton decay channels (specifically ) and the QCD axion mass.
This review article outlines the theoretical foundations and summarizes recent experimental efforts to detect exotic spin-dependent interactions mediated by light particles like axions and Axion-Like Particles, which are proposed solutions to the strong CP problem, dark matter, and other physics beyond the Standard Model.
This paper investigates the impact of wave packet decoherence, open quantum system decoherence, and invisible neutrino decay on neutrino oscillations, demonstrating that the first JUNO data can already place competitive bounds on these non-standard scenarios while maintaining robust measurements of standard oscillation parameters.
This study extends the dynamical quasiparticle model to include inelastic gluon-radiation processes, finding that while these radiative channels systematically reduce transport coefficients like shear viscosity and electric conductivity compared to elastic-only results, the effect remains moderate in the thermal regime and yields predictions compatible with lattice-QCD estimates at zero baryon chemical potential.
This paper investigates the Grimus-Neufeld Model, an extension of the Standard Model with an additional Higgs doublet and a Majorana neutrino, by calculating the tree-level two-body decays of its heavy scalars and the lifetime of the pseudoscalar in the Inert Doublet Model limit to evaluate its potential as a dark matter candidate.
This paper presents AgentRivet, an automated workflow utilizing Large Language Models to extract physics analysis details from journal publications and generate Rivet routines, thereby addressing the significant gap in coverage for model-independent measurements in particle physics.
This paper presents the first calculation of heavy quark transport and thermal dilepton production in a QGP using second-order viscous corrections derived from the Chapman-Enskog expansion, revealing that these corrections significantly suppress drag forces and enhance early-time dilepton yields while demonstrating that observable modifications depend on the complex interplay between correction magnitude, momentum dependence, and the specific momentum weighting of each observable.
This paper calculates the form factors for and transitions using three-point QCD sum rules with various condensate contributions, and subsequently predicts the decay widths and branching ratios for several two-body nonleptonic decay processes to provide insights into heavy-quark dynamics.
This paper proposes that axion dark matter induces electromagnetic radiation in conductors via the chiral magnetic effect, demonstrating that existing cavity experiments can constrain the axion-electron coupling to and suggesting that replacing copper walls with carbon-based conductors could enhance sensitivity to over a wider mass range.
This paper proposes a novel mechanism for primordial Dirac leptogenesis occurring during the post-inflationary reheating phase, where an inflaton-generated asymmetry is transferred to chiral neutrinos and subsequently to baryons via sphalerons, offering a testable prediction for the effective number of relativistic species () while naturally accommodating small neutrino Yukawa couplings.
