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.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This work investigates the cause of the non-monotonic magnetic-field-dependent charged-pion excitations in the NJL model and shows that while certain mass-generation schemes cannot reproduce the reversal observed in lattice calculations, direct determinant and near-pole methods robustly confirm this behavior as a genuine quasiparticle mixing effect between pions and rho mesons.
This paper demonstrates that incorporating one-loop finite corrections into fermion mass fits within the minimal $SO(10)$ grand unified theory is essential for precision, as these radiative effects induce significant (30–40%) deviations in neutrino observables that render conventional tree-level analyses insufficient for reliable parameter space exploration.
This paper investigates leading Generalized Transverse Momentum Dependent parton distributions (GTMDs) within the bag model to demonstrate theoretical consistency, establish analytical sum rules for orbital angular momentum via the Ji sum rule and GTMD , and reveal a deeper connection between orbital angular momentum and pretzelosity.
This paper reinterprets the Hagedorn temperature in string theory as a nonequilibrium dynamical bottleneck using Steepest-Entropy-Ascent Quantum Thermodynamics, demonstrating how the exponential density of states and its algebraic prefactor govern the slowing-down of effective intensive variables and the breakdown of thermodynamic descriptions.
This work presents a comprehensive lattice-QCD determination of the flavor-singlet and strange axial form factors of the nucleon using CLS gauge configurations with -improved Wilson fermions, providing a complete error budget for the extrapolations with respect to chiral symmetry, the continuum limit, and infinite volume, with a specific focus on the treatment of discontinuous contributions.
This paper introduces BRICKS, a differentiable, compositional neural surrogate based on hybrid discrete-continuous transformers and Riemannian Flow Matching that enables zero-shot, high-speed simulation of radiation-matter interactions by composing next-particle prediction kernels to model unseen large-scale material distributions.
This paper presents a novel, nonparametric pixel-based framework that leverages generative AI and Bayesian inference to simultaneously extract transverse momentum dependent (TMD) parton distributions and their evolution kernels, thereby enabling unbiased 3D partonic imaging while rigorously characterizing uncertainties and resolving inherent degeneracies.
This study models the transport of cosmic rays and the gamma-ray emission from SNR G296.5+10.0 and the associated CCO 1E 1207.4-5209, showing that the Cherenkov Telescope Array Observatory (CTAO) can detect the characteristic hadronic and leptonic emissions of this unique system to provide, for the first time, constraints on particle acceleration in environments of luminosity-weak CCO supernova remnants.
This work demonstrates that employing a fully covariant formalism to account for previously overlooked gauge dependencies reveals that the formation of primordial black holes and scalar-induced gravitational waves from first-order phase transitions is strongly suppressed, thereby calling into question their suitability as an explanation for the recent signals from pulsar timing arrays.
This paper demonstrates that thermal leptogenesis in the canonical type-I seesaw framework retains a "memory" of asymmetries generated by heavier right-handed neutrinos through flavor-projection effects, which partially survive the washout of the lightest neutrino and significantly modify the final asymmetry beyond the predictions of classical Boltzmann equations.
