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 defends Large-Momentum Effective Theory (LaMET) against recent claims that it suffers from an unquantifiable inverse problem, arguing that physics-guided systematic extrapolation remains the most reliable method for estimating uncertainties in parton distribution calculations even when lattice data precision is suboptimal.
This paper reviews how recent advancements in Large Momentum Effective Theory (LaMET), including improved renormalization schemes, higher-order matching kernels, and novel lattice operators, are enhancing the precision and reliability of first-principles lattice QCD calculations for proton parton distributions.
This paper demonstrates that the Wilson formulation of fermions in lattice gauge theory unifies the description of chiral anomalies by showing how the discrete Dirac operator's eigenvalue structure, specifically the collision of complex pairs outside the perturbative region, facilitates transitions between topological sectors.
This paper calculates the leading-order mixed-action chiral perturbation theory constant using -flavor lattice ensembles, revealing that the fermion action dominates the results while the gauge action has a measurable secondary effect and charm quark loops are negligible.
This paper presents the first lattice calculation of a two-to-two particle matrix element using pionless effective field theory to demonstrate that while finite-volume formalism is unnecessary for deep-bound states, it is critical for accurately determining the infinite-volume elastic form factors and charge radii of shallow-bound states like the deuteron.
This paper demonstrates that symmetry-twisted partition functions computed via the tensor renormalization group framework effectively detect spontaneous symmetry breaking in three-dimensional models, determine the BKT transition in two dimensions, and successfully identify phase transitions in generalized two-dimensional models.
This paper reviews recent advancements in tensor network renormalization group methods, highlighting their potential to overcome sign and complex action problems in lattice field theories and their growing application to studying quantum chromodynamics at finite temperature and density, as well as universal critical behaviors via conformal field theory insights.
This paper demonstrates that the Serreau–Tissier replica sector in Yang–Mills theories can dynamically generate a Gribov–Zwanziger-type horizon functional through the expansion of the Faddeev–Popov determinant, thereby providing a microscopic mechanism for the emergence of the Gribov scale that yields either a Curci–Ferrari mass or a refined Gribov–Zwanziger decoupling propagator depending on the replica symmetry phase.
This paper demonstrates that normalizing flows can significantly reduce the variance of lattice QCD observables involving gluonic operators by factors of 10 to 60, offering a computationally efficient method that maintains performance across different lattice volumes.
This paper presents progress in a correlated lattice-QCD analysis using HISQ fermions to address the CKM unitarity deficit by updating light-meson decay constants via staggered chiral perturbation theory and reanalyzing kaon semileptonic form factors to estimate their correlations.
