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 reviews recent advances in lattice QCD calculations of hadron structure, specifically for pions, kaons, and nucleons, highlighting how these theoretical developments provide essential insights to inform the scientific agenda of the Electron-Ion Collider.
This paper outlines the key concepts of the Worldvolume Hybrid Monte Carlo method and presents its extension to group manifolds, establishing a rigorous framework for applying this efficient algorithm to lattice gauge theories while avoiding the ergodicity issues of Lefschetz-thimble approaches.
This paper investigates universal features of chiral symmetry breaking in large- QCD by comparing non-perturbative lattice Monte Carlo calculations of the low-lying Dirac spectrum with chiral Random Matrix Theory predictions, utilizing twisted volume reduction to reach and extract the large- chiral condensate.
This paper establishes precise scale settings for SU() Yang--Mills theories across various values and the large- limit by combining gradient flow with twisted boundary conditions and Parallel Tempering to overcome topological freezing, thereby enabling accurate determinations at lattice spacings as fine as 0.025 fm and validating large- volume reduction.
This paper employs a symmetry-preserving vector-vector contact interaction to calculate the four kaon transverse momentum dependent parton distribution functions (TMDs), offering insights into the roles of emergent hadron mass, Higgs-boson coupling effects on strange quark mass, gauge link models regarding positivity constraints, and scale-evolution impacts on the Boer-Mulders function.
This paper constructs a set of conserved non-singlet charges for the 3+1 dimensional staggered fermion Hamiltonian by decomposing fermions into Majorana components and utilizing lattice translation symmetries, demonstrating that while these charges are non-commutative on the lattice, they generate axial SU(2)_L × SU(2)_R transformations in the continuum limit.
This paper reconstructs vector and axial charge operators within the Wilson fermion formalism to formulate a lattice gauge theory with exact axial symmetry and quantized chirality, enabling the study of Symmetric Mass Generation in 3-4-5-0 models.
This paper presents ongoing lattice studies of two-dimensional maximally supersymmetric Yang-Mills theory, including the construction of a supersymmetry-preserving lattice action and the development of new simulation routines, to facilitate numerical tests of gauge-gravity duality and explore non-perturbative phenomena.
Using high-statistics lattice QCD simulations with twisted mass fermions at physical quark masses, the authors determine non-zero nucleon strange electromagnetic form factors and radii in the continuum limit while finding the charm electromagnetic form factors consistent with zero.
This paper presents the first continuum-limit calculation of nucleon strange electromagnetic form factors using lattice QCD simulations with physical quark masses, yielding results with statistical and systematic uncertainties an order of magnitude smaller than current experimental determinations.
