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 introduces a momentum rescaling framework that explains the unexplained rise-and-fall pattern of radial flow fluctuations in the quark-gluon plasma by factorizing them into a kinematic component driven by spectral shape transitions and a dynamical component that reveals significant medium-dependent deviations in LHC and RHIC collisions.
This paper proposes a strategy for detecting the broadband Cosmic Axion Background using multi-cavity arrays that exploit spatial correlations of the axion-induced electric field, finding that while current ADMX upgrades lack coherent enhancement, optimized stacked, wide-base geometries could improve sensitivity by an order of one.
This paper proposes and evaluates methods for generating ultra-fast, precise amplitude surrogates for LHC event generation by investigating noise reduction in network ensembles, establishing evidential regression as a sampling-free uncertainty quantification tool, and demonstrating that learned uncertainties effectively identify numerical noise and data gaps in amplitude regression.
This paper proposes a CP-conserving SO(3) parameterization of the neutrino mixing matrix that yields either "democratic" or near-maximal mixing angles depending on the CP phase, offering a testable alternative to the standard PMNS framework for future neutrinoless double beta decay experiments.
This paper proposes that TeV-scale quasi-Dirac fermions, arising from lepton-symmetry violations in unified theories, simultaneously generate small radiative neutrino masses and provide a stable dark matter candidate, with their tiny mass splitting ensuring consistency with experimental constraints on dark matter detection and charged lepton flavor violation.
This paper proposes a minimal -symmetric type-II seesaw model that generates a neutrino mass sum rule fully determining the absolute mass spectrum and predicting inverted ordering, specific Majorana phases, and a maximal neutrinoless double beta decay rate, while simultaneously suppressing muon flavor-violating processes through an approximate triality symmetry in the charged lepton sector.
This paper demonstrates that while the Krauss-Nasri-Trodden (KNT) model can satisfy low-energy experimental constraints, a significant portion of its viable parameter space is ruled out by vacuum stability conditions when renormalization group effects are considered, leaving most of the remaining region testable through future charged lepton flavor violating experiments.
This paper reviews the current status and future prospects of axion superradiance, a phenomenon where light bosonic fields amplify around rotating compact objects to constrain axion masses and probe non-gravitational interactions, while emphasizing the necessity of accounting for complex astrophysical environments.
This paper proposes and validates via lattice simulations a novel Grand Unified Theory-scale first-order phase transition within Starobinsky inflation, featuring a dynamically evolving potential barrier that suppresses early bubble nucleation while triggering massive nucleation at the end of inflation to successfully resolve the graceful exit problem and produce a distinctive gravitational-wave spectrum.
This paper derives a fluctuation-dissipation relation for an energetic light quark in a non-perturbative thermal gluon plasma by connecting the longitudinal drag coefficient to longitudinal and transverse diffusion coefficients and the thermal gluon condensate through complex-valued transport functions and contour-integration techniques.
