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 nonlocal realization of the Stueckelberg portal connecting the Standard Model and a Dark Sector via a massive dark photon, analyzing its phenomenological implications for meson decays and deriving experimental constraints on the model's parameters, including the nonlocality scale.
Using Planck 2018 CMB data, this paper demonstrates that Bayesian constraints on dark matter-proton scattering are biased by prior-volume effects that overestimate limits, and thus recommends supplementing them with frequentist profile-likelihood analyses to obtain prior-independent results.
This paper presents a comprehensive analysis of cosmic ray signals from asteroid-mass primordial black holes, incorporating full transport effects and new multi-wavelength data to derive leading constraints on their contribution to dark matter while testing various spin and mass distribution assumptions.
This paper introduces an uncertainty-aware machine learning framework that successfully classifies the pole structures of hadronic scattering amplitudes, achieving high accuracy on synthetic data and inferring a four-pole structure for the state in experimental LHCb data.
This paper presents a comprehensive phenomenological analysis of the Ho calorimetric electron capture spectrum from the HOLMES experiment, modeling the unfolded data as a sum of Breit-Wigner resonances and shake-off continua to accurately describe spectral features, validate against theoretical calculations, and provide a robust framework for future neutrino mass experiments.
This paper demonstrates how machine learning-based simulation techniques can systematically optimize precision-theory-compatible observables, specifically identifying that isosceles right-triangle energy 3-point correlators maximize sensitivity to the top quark mass while remaining computable to high precision.
This paper investigates nonmaximal symmetry breaking patterns within a supersymmetric theory, demonstrating that specific patterns allow for gauge coupling unification below the Planck scale while explaining fermion mass hierarchies, whereas a distinct pattern is ruled out due to the presence of unrealistic massless vectorlike quarks.
This study employs long-term general-relativistic simulations to demonstrate that axion-photon coupling can induce detectable cooling effects in the late-phase neutrino signals of core-collapse supernovae, potentially allowing future observations by Super-Kamiokande to identify axion-like particles even with coupling constants below conventional energy-loss limits.
This paper presents state-of-the-art NNLO QCD predictions for heavy-quark pair production in direct photon fusion by applying the Local Unitarity formalism to handle infrared singularities and combining these results with NLO electroweak corrections and NLP Coulomb resummation for top, bottom, and charm quarks.
This paper demonstrates that considering axionlike particle production from the full electromagnetic shower in beam dump targets, rather than just primary beams or specific meson decays, yields order-of-magnitude enhancements in detectable signals, thereby significantly expanding the sensitivity reach of the SHiP and BDX experiments to previously unexplored regions of ALP parameter space.
