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 proposes a factorization framework and effective two-qubit description to access quantum information in photon pairs at high-energy lepton colliders, demonstrating that existing Belle data could achieve a 7.4 violation of Bell inequalities while also enabling precise measurements of quantum discord and nonstabilizerness.
This paper reviews theories involving confining dark sectors, highlighting their potential to explain dark matter candidates, the abundance similarity puzzle, and various experimental discovery channels, while advocating for further exploration of this class of models.
This paper presents a magnetically levitated ferromagnetic vector force sensor capable of distinguishing spin-dependent exotic interactions by mapping forces to distinct translational modes, thereby enabling sensitive searches for parity-violating electron-electron couplings in the previously inaccessible millimeter-scale range.
This paper introduces a numerical polology framework that samples coupling spaces to discover perturbative, ghost-free dark sector models and validates them against observational constraints from black hole superradiance, dynamical dark energy, and gravitational waves.
This paper presents a model-independent extraction of the nucleon axial form factor by fitting NNLO chiral perturbation theory with explicit resonance contributions to lattice QCD data, successfully describing pion-mass and momentum dependencies to yield precise physical-point values for the axial charge and radius.
The paper introduces LUNAR, a fast and open-source Monte Carlo generator that simulates two-body bound-nucleon decays in liquid argon by incorporating diverse nuclear models and intranuclear cascade effects to quantify how final-state interactions and nuclear binding reshape decay kinematics for the DUNE experiment.
This paper investigates the phenomenology of a mixed dark photon and axion-like particle portal, demonstrating how the exotic cascade decay can transform long-lived dark photon signatures into experimentally accessible displaced multi-photon events at future high-luminosity lepton colliders like the FCC-ee.
By analyzing suppression in high-multiplicity $pp$ and Pb collisions through six differential constraints, this study rules out mechanisms driven solely by local track density or total multiplicity, instead supporting an early, globally correlated, topology-sensitive suppression pattern consistent with a deconfined, pre-hadronic environment.
This paper employs the functional renormalization group method within a linear sigma model to investigate the phase structure and anomaly effects in dense two-color QCD, revealing that while anomaly couplings for mesons are enhanced by the quark chemical potential, the topological susceptibility is suppressed at high densities and chiral partners exhibit mass degeneracy upon chiral restoration.
This paper predicts a sizable and robust Sivers asymmetry in back-to-back -photon and -jet production at the Electron-Ion Collider using a TMD factorization framework with CSS evolution, demonstrating that the asymmetry serves as a reliable probe of the gluon Sivers function largely independent of the specific long-distance matrix element sets used.
