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 nonperturbatively constructs a gauge-invariant measure for overlap fermions on four-dimensional Euclidean lattices within a class of nonabelian chiral gauge theories, including the Standard Model, by demonstrating that comparing chiral projectors on admissible gauge fields yields an exponentially local current that satisfies the global properties required for Lüscher's reconstruction of a smooth fermion measure.
This study utilizes Monte Carlo simulations to demonstrate that the trigger transverse momentum dependence of strangeness enhancement in high-multiplicity proton-proton collisions serves as a critical discriminator between the core-contribution suppression mechanism in EPOS-LHC and the local string-overlap mechanism in PYTHIA8 with color ropes.
This paper introduces the multi-reference relative representation (M3R) framework to unify and systematically compare distinct collider event metrics, revealing how they resolve complementary geometric structures and decision boundaries within a cohesive coordinate system.
This paper presents a double-dilaton holographic model of QCD that incorporates large- corrections to describe the running coupling constant across energy scales and successfully reproduces linear Regge trajectories for various meson states in agreement with experimental data.
This paper presents next-to-next-to-leading-order QED initial-state corrections, including photonic and vacuum-polarisation effects, for the process within the McMule framework, demonstrating that while total cross-section corrections are typically below the percent level, they can be locally significant and must not be neglected, especially at higher energies.
This paper proposes that combining nuclear recoil data from experiments like LUX-ZEPLIN with solar neutrino observations can resolve the composition of singlino-Higgsino dark matter in the NMSSM, as solar neutrinos provide critical constraints on ground-state configurations that nuclear recoils alone cannot distinguish.
This paper introduces \texttt{kwqft}, a performance-portable Kokkos-based implementation of Wilson pure gauge Monte Carlo simulations for Yang-Mills theory that supports arbitrary dimensions and multiple hardware backends while achieving accuracy and competitive performance across diverse high-performance computing systems.
This paper derives a family of exact sum rules for spin-1 target tensor structure functions based on Siegert relations, establishing a superconvergence condition that connects theoretical predictions with experimental data and offers a direct strategy for measurement at facilities like JLab and the future EIC.
This paper employs Padé approximants constrained by large- results to estimate the unknown QCD correction to the Higgs boson decay into gluons as , a prediction that significantly reduces the residual renormalization-scale dependence of the decay rate.
This study utilizes quantum-kinetic formalism to demonstrate that frequency chirping in rotating electric fields induces a pronounced helicity asymmetry in Schwinger pair production, causing right- and left-helicity electrons to preferentially populate opposite momentum half-spaces, with the magnitude of this effect depending critically on pulse symmetry and the specific configuration of dynamically assisted two-color fields.
