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 reformulates the strong coupling expansion of large- QCD as constrained one-dimensional spin chains, demonstrating that while specific subsectors remain integrable, the full system loses integrability due to zigzag symmetry constraints, yet still successfully estimates the roughening transition point.
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.
This paper reports on large-scale lattice studies of the Corrigan--Ramond large- 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.
This paper utilizes state-of-the-art lattice calculations and experimental form factor data to visualize momentum flow and color-Lorentz forces within the nucleon, revealing that the gluon anomaly generates a critical attractive force on quarks comparable in strength to heavy-quark confinement.
This paper proposes a "field digitization scaling" framework that treats the number of discrete field values 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.
This paper challenges the interpretation of the nucleon's momentum current density as a continuous medium's pressure and shear forces, arguing instead that color interactions are long-ranged and that only the isotropic vacuum pressure term derived from the QCD trace anomaly effectively provides the confining potential for quarks.
This paper presents the first next-to-leading-logarithmic QCD analysis of electromagnetic corrections to the semileptonic weak Hamiltonian, calculating mixed corrections to the vector coupling to yield a refined radiative correction value that enhances the consistency of first-row CKM unitarity tests.
This paper employs bond-weighted tensor renormalization group calculations to demonstrate that dimensionless partition-function ratios for the Ising and Potts models obey finite-size scaling and yield critical values consistent with conformal field theory predictions, while also revealing logarithmic corrections in the four-state Potts model.
Using QCD sum rules, this study calculates the mass and width of the axial-vector hadronic molecules and with quark content , predicting a mass of approximately 15.8 GeV and an unstable width of about 114 MeV to guide future experimental searches for fully heavy molecular structures.
This paper introduces a new universality paradigm for hybrid qubit-qumode quantum computing based on trigonometric continuous-variable gates, demonstrating their effectiveness through a deterministic ancilla-based implementation and a successful simulation of the lattice sine-Gordon model, including ground state preparation, real-time dynamics, and kink profile extraction.
