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.

Simulating Lattice Gauge Theories with Virtual Rishons

This paper introduces a novel virtual rishon framework that enforces gauge symmetry via intermediate quantum-link representations to enable scalable simulations of lattice gauge theories in d+1 dimensions using both classical tensor networks and near-term quantum hardware, validated by benchmarking on the multi-flavor Schwinger model and 2D string tension.

Discretisation effects of gradient flows in QCD-like theories on the lattice

This paper reports on large-scale lattice studies of the Corrigan--Ramond large-NCN_C limit of Yang-Mills theory, utilizing gradient flows to analyze topological charge properties and discretisation effects, ultimately concluding that current simulations at lattice spacings of 0.08–0.11 fm are subject to approximately 10% discretisation errors.

Field digitization scaling in a ZNU(1)\mathbb{Z}_N \subset U(1) symmetric model

This paper proposes a "field digitization scaling" framework that treats the number of discrete field values NN as a renormalization group coupling, successfully applying it to relate the 2D classical clock model to the XY model and its quantum gauge theory counterpart to enable continuum limit analysis in quantum simulations.

Beyond Leading Logarithms in gVg_V: The Semileptonic Weak Hamiltonian at O(ααs2)\mathcal{O}(α\,α_s^2)

This paper presents the first next-to-leading-logarithmic QCD analysis of electromagnetic corrections to the semileptonic weak Hamiltonian, calculating mixed O(ααs2)\mathcal{O}(\alpha\alpha_s^2) corrections to the vector coupling gVg_V to yield a refined radiative correction value that enhances the consistency of first-row CKM unitarity tests.
