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 presents a thermodynamically consistent mean-field model of interacting relativistic charged bosons at finite temperature and isospin density, formulated in an Extended Canonical Ensemble with repulsive and interactions, which successfully reproduces lattice QCD results for isospin density, energy density, and trace anomaly using a single fitted parameter.
This paper provides a brief overview of tensor-polarized parton distribution functions and fragmentation functions for spin-1 hadrons, highlighting unique observables like the , structure functions and gluon transversity that offer insights into hadron dynamics beyond simple nucleon models.
This paper theoretically demonstrates that nuclear modifications to the longitudinal-transverse structure function ratio in the deuteron, arising from transverse Fermi motion, result in a few-percent effect that must be accounted for in high-energy nuclear data analysis and is expected to be confirmed by upcoming experiments at JLab.
This paper presents a sign-free path-integral Monte Carlo framework for Kitaev quantum doubles that utilizes non-invertible 1-form symmetries and a matterization isometry to numerically demonstrate first-order transitions driven by non-Abelian anyon condensation and confinement in gauge-Higgs theories.
This paper reviews three decades of progress in generalized parton distributions (GPDs), highlighting significant advancements in experimental measurements, sophisticated phenomenological analyses, theoretical refinements, and lattice QCD calculations that collectively enable three-dimensional nucleon tomography and a deeper understanding of the nucleon's mass, spin, and internal forces.
This paper investigates the structure of the meson by calculating its valence-quark generalized parton distribution functions and form factors using a theoretical framework based on the exponential representation scheme combined with the modified chiral quark model, comparing the results with experimental data and other models.
This paper presents the first numerical lattice study of Sp(4) gauge theory with two fundamental Dirac fermions using the Möbius domain-wall fermion formulation within the Grid framework, demonstrating that this approach achieves order-of-magnitude gains in continuum extrapolation efficiency compared to Wilson fermions with moderate computational resources.
This paper reviews how rapid advancements in quantum computing and sensing technologies are reshaping particle physics by enabling the study of nonperturbative dynamical processes and facilitating novel searches for physics beyond the Standard Model with unprecedented sensitivity.
This thesis presents two complementary numerical investigations of phase transitions in lattice field theories: utilizing GPU-accelerated higher-order tensor renormalization group methods to map the phase diagram of the two-dimensional generalized XY model, and developing a configurational temperature estimator based on action gradients and Hessians to validate thermal sampling in compact U(1) lattice gauge theories.
This paper demonstrates that the computability of Generalized Parton Distributions (GPDs) in Lattice QCD can be extended to the critical regions by relaxing large momentum expansion conditions at high , thereby enabling the first lattice observation of the expected partonic threshold behavior and providing new predictions for GPDs in the distribution-amplitude-like region.
