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 applies transfer learning to fine-tune deep neural networks pretrained on carbon-12 data, successfully constructing robust, data-driven models for inclusive electron-nucleus cross sections across various nuclei that outperform existing phenomenological models while systematically analyzing the impact of fine-tuning depth, data availability, and kinematic coverage.
This paper presents a nonperturbative functional renormalization group framework for Higgs-singlet models that utilizes physics-informed neural networks to solve the Wetterich flow equation without polynomial expansion, successfully reconstructing finite-temperature effective potentials while highlighting the critical necessity and current limitations of soft consistency constraints for selecting physically sensible solutions.
This paper evaluates the shear viscosity and heavy quark spatial diffusion coefficient in a Quasi-Particle Model using novel lattice QCD data, employing both Chapman-Enskog and Green-Kubo formalisms to compare strong and weak coupling regimes.
This study utilizes second-order perturbation theory and Monte Carlo integration to calculate impact-parameter-dependent cross sections for simultaneous free and bound-free pair production in relativistic collisions at the LHC, offering new theoretical predictions to test quantum electrodynamics in strong electromagnetic fields.
This paper proposes that a specific high-energy nuclear recoil event observed by the LUX-ZEPLIN experiment can be explained by a 1.1 TeV Higgsino inelastic dark matter model with a 350 keV mass splitting, which predicts a nearly degenerate chargino that decays into a sub-centimeter tracklet within the detector, a signature currently unconstrained by the LHC but testable at future high-energy colliders.
This paper theoretically investigates backward Compton scattering between a vortex photon and a plane-wave electron where both final-state particles are projected onto vortex states, deriving analytical cross-sections and demonstrating that the process enables the generation and control of high-energy vortex photons and electrons through distinct energy-angle correlations and topological-charge-dependent interference patterns.
This paper classifies dimension-7 baryon-number-violating operators within chiral perturbation theory to systematically analyze nucleon decays, deriving improved lifetime limits for three-body modes from existing two-body constraints and proposing a concrete ultraviolet model that generates these processes.
This paper proposes a radiative neutrino mass model based on the T4-3-i-C1 topology featuring an inert doublet and scalar/fermion triplets that simultaneously explains neutrino masses (predicting one massless neutrino), provides a CP-even scalar dark matter candidate, and yields distinctive collider signatures from long-lived triplet particles.
This paper extends a method using elliptic generalizations of leading singularities to construct a rational basis for elliptic Feynman integrals, demonstrating that the off-diagonal blocks of their differential equations possess a universal -dependent structure preserved under decoupling transformations.
This paper proposes that the high-energy candidate event LZ230616 observed by the LUX-ZEPLIN experiment could be explained by inelastic scattering between Majorana dark matter states mediated by an axion-like particle coupled to gluons, identifying specific mass and coupling parameters that reproduce the observed recoil energy while highlighting the model's sensitivity to halo velocity constraints.
