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.

Below are the latest papers in High Energy Physics – Lattice, curated directly from arXiv and ready for you to explore.

A Machine Learning study of the two-dimensional antiferromagnetic qq-state Potts model on the square lattice

This study employs a specifically trained, minimal multilayer perceptron to successfully identify the critical temperatures of the two-dimensional antiferromagnetic qq-state Potts model on a square lattice, revealing that the q=3q=3 case is critical only at zero temperature while the q=4,5,6q=4,5,6 cases remain disordered across all temperatures.

Lattice determination of the QCD low-energy constant 7\ell_{\scriptscriptstyle{7}}

This paper presents a non-perturbative lattice QCD determination of the scheme- and scale-independent low-energy constant 7\ell_7 using Nf=2+1N_f=2+1 staggered fermion simulations, yielding a final result of 2.79(61)×1032.79(61) \times 10^{-3} that significantly improves upon previous estimates.

BπB \to \pi, B(s)D(s)B_{(s)} \to D_{(s)} from 2+1+1 Flavor Lattice QCD

This paper presents a 2+1+1-flavor lattice QCD calculation of hadronic form factors for BπB \to \pi and B(s)D(s)B_{(s)} \to D_{(s)} semileptonic decays using highly improved staggered quarks on MILC ensembles, aiming for a percent-level determination of these form factors to enable high-precision measurements of Vcb|V_{cb}|.
