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 quantum algorithmic framework utilizing maximal-tree gauge fixing and quantum singular value transformation to efficiently simulate non-Abelian Yang-Mills theories, including QCD, with proven polynomial scaling in system parameters and simulation precision.
This paper presents a physics-informed quantum computing framework for a (2+1)-dimensional lattice gauge theory that variationally prepares the gauge vacuum and employs Wilson-loop quantum subspace expansion, eigenvector continuation, and quench dynamics to systematically construct and characterize localized glueball-like excitations, offering a transferable approach for future non-Abelian studies.
This paper utilizes light-cone QCD sum rules to calculate the radiative decay widths of heavy-strange axial-vector mesons, demonstrating that the significant difference in decay patterns between the lower and higher states arises from the constructive and destructive interference of - mixing, respectively.
This paper demonstrates that the modular commutator, previously established as a measure of chiral central charge in gapped 2D systems, remains well-defined and yields a robust half-quantized value in gapless phases hosting massless Dirac fermions, thereby providing an information-theoretic measurement of the parity anomaly.
This paper demonstrates that the trace-anomaly-subtracted -mass for heavy quarks is a unique, renormalon-free mass definition that can be precisely related to the pole mass via a five-loop perturbative formula and determined from lattice QCD, making it an ideal reference scheme for unifying quark mass calculations across different approaches.
This study demonstrates that while disorder in a U(1) quantum link model on a ladder can destroy the criticality of the nonzero mass phase, the Ising universality class and the symmetry-protected topological phase remain robust against weak disorder, contrary to predictions from the Harris criterion.
This paper employs the functional renormalisation group to demonstrate that the critical gauge coupling for dynamical chiral symmetry breaking depends strongly on the number of fermion flavors, suggesting a first-order quantum phase transition at that challenges the conventional Miransky/BKT scaling and walking regime scenarios.
Using QCD sum rules, this study calculates the photon and gluon gravitational form factors of the proton, revealing that the gluon mass radius is smaller than the photon's, which indicates a more localized gluonic energy distribution within the proton.
This paper presents a no-go theorem demonstrating that standard finite-width neural network ensembles cannot consistently realize either quantum or effective field theories on a computer due to failures in reflection positivity and scale separation, with only specific infinite-width limits or relaxations of finite variance and rotation invariance offering potential escapes.
This paper presents a novel lattice QCD calculation of the neutron electric dipole moment induced by the QCD theta term using the Feynman-Hellmann theorem and background electric fields, yielding a result that confirms the strong-CP problem by constraining the theta angle to .
