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 finite-temperature lattice study of Sp(4) Yang-Mills theory using the Logarithmic Linear Relaxation algorithm to characterize its first-order confinement/deconfinement phase transition, estimate discretization and finite-volume artifacts, and establish bounds for the continuum theory's critical coupling, specific heat, and surface tension.
This paper introduces a novel gauge-equivariant neural-network architecture that effectively mitigates critical slowing down in Lattice QCD simulations by preconditioning the Dirac equation, demonstrating robust performance across varying topological charges and volumes while transferring successfully to unseen gauge configurations without retraining.
The RC* collaboration utilizes their openQxD code to present preliminary baryon mass results, including the first computation of additional partially connected contributions for the baryon, from QCD+QED simulations employing C-periodic boundary conditions at an unphysical pion mass of approximately 400 MeV.
This paper presents the first lattice QCD calculation of the electromagnetic form factors for the tetraquark, providing evidence that its internal structure comprises a compact heavy diquark and a light antidiquark.
This paper presents the RBC/UKQCD collaborations' current status on calculating isospin breaking corrections to the hadronic vacuum polarization using stochastic coordinate sampling to efficiently construct all necessary Wick contractions and employing various lattice QED formulations to better estimate finite-volume uncertainties.
This paper presents a systematic QCD sum-rule analysis of charged kaons in hot and dense matter, deriving their in-medium masses and decay constants to reveal a significant mass splitting driven by baryonic interactions and identifying a critical density threshold that signals the onset of chiral symmetry restoration.
This paper presents a next-to-next-to-next-to-leading order calculation of the three-loop hadronic vacuum polarization in chiral perturbation theory, achieving unprecedented precision for low-energy contributions and providing a framework to improve lattice QCD computations of the muon magnetic moment.
This paper presents an improved determination of the light-quark connected hadronic vacuum polarization contribution to the muon anomalous magnetic moment using a fine 2+1+1 HISQ lattice ensemble, achieved by implementing a sparsening strategy within the low-mode averaging framework to efficiently reduce the computational cost of the dominant low-low correlator component while preserving signal quality.
This paper presents an update on the calculation of the light-quark, connected hadronic vacuum polarization contribution to the muon anomalous magnetic moment using flavor HISQ ensembles with physical pion mass, highlighting preliminary results and algorithmic improvements for computing vector-vector correlation functions.
This study utilizes lattice QCD simulations to analyze the Dirac eigenspectrum at finite temperature, revealing how intermediate level statistics and Thouless conductance serve as diagnostics for the interplay between chiral symmetry restoration and disorder-driven localization, particularly in the context of the effective restoration of the anomalous symmetry.
