Hep-Lat, short for High Energy Physics – Lattice, explores the fundamental forces of nature by simulating particle interactions on a digital grid. Instead of relying solely on abstract equations, researchers in this field use powerful computers to model how quarks and gluons bind together, offering deep insights into the structure of matter that are often impossible to derive analytically.
Gist.Science ensures these complex discoveries from arXiv remain accessible to everyone. We process every new preprint in this category as it is posted, providing both plain-language explanations for the curious and detailed technical summaries for experts. This dual approach bridges the gap between cutting-edge simulation work and broader scientific understanding.

This paper demonstrates that enforcing -channel unitarity in high-energy elastic $pp$ scattering models significantly increases the extracted dynamical gluon mass scale from approximately 300–420 MeV to 750–1100 MeV, revealing that the physical infrared scale is a unitarity-dressed quantity determined jointly by the nonperturbative gluon propagator and multiple-exchange dynamics.
This paper presents a comprehensive lattice QCD study using RBC/UKQCD ensembles to determine the masses, decay constants, and compositeness parameters of positive- and negative-parity charm-strange and bottom-strange mesons, providing the first lattice results for and and confirming that the positive-parity states are predominantly molecular in nature.
This paper proposes a "blending" algorithm that combines spatial low-frequency mode projections with stochastic high-frequency estimates to efficiently compute all-to-all fermion propagators, enabling high-precision first-principles predictions of nucleon axial charges and pion form factors in quantum chromodynamics.
This paper presents an improved, finite-sum expression for the partial-wave projection of the one-particle exchange process in relativistic three-body scattering of massive, spinless particles, which accurately reproduces known physical properties while significantly enhancing computational efficiency for constructing robust amplitude analyses.
This paper introduces a mixture of sector-resolved samplers (MSRS), a generative model that combines sector-specific training with bijective topological shifts to explicitly resolve topological sectors and accurately compute their relative weights, thereby overcoming the topological freezing problem that plagues traditional Markov Chain Monte Carlo methods in lattice gauge theories.
This paper investigates the digitization of U(1) gauge fields by Z(N) subgroups in 2+1 dimensions using anisotropic Euclidean lattices to define trajectories for approaching the Hamiltonian limit, revealing that freezing transitions and significant finite-N deviations persist even in this limit, thereby providing essential benchmarks for controlling systematic errors in quantum simulations of gauge theories.
Using QCD two-point sum rules, this study quantitatively analyzes how the mass and decay constant of the meson in a hot and dense medium initially increase with temperature or baryon chemical potential before reaching a maximum and eventually vanishing at critical values that shift to lower thresholds as the opposing parameter increases.
This paper systematically investigates baryon-baryon interactions in singly bottomed dibaryon systems using the chiral quark model, revealing that low-isospin and decuplet-decuplet channels favor stronger attraction and identifying numerous potential bound states that warrant further experimental verification.
This paper computes the equation of state for dense, magnetized QCD matter using lattice simulations with physical quark masses and a novel -expansion scheme to perform analytic continuation from imaginary chemical potentials, thereby circumventing the sign problem and reducing systematic errors to provide tabulated results for heavy-ion phenomenology.
This paper presents a lattice QCD calculation of the CP-violating pion-nucleon coupling induced by the QCD -term using 2+1+1-flavor HISQ ensembles, demonstrating that while direct extraction is noisy due to excited state contamination, applying the axial Ward identity and chiral perturbation theory yields a precise result of .
