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 proposes and validates a hybrid algorithm that embeds Generalized-thimble HMC within Worldvolume HMC to overcome ergodicity limitations in thin-layer simulations, thereby enabling efficient, large-scale studies of the doped Hubbard model with controlled statistical errors.
This paper demonstrates that conditional Masked Autoregressive Flows can efficiently interpolate lattice QCD observables across bare parameters to locate phase boundaries and critical points, offering a practical tool to reduce the computational cost of Monte Carlo simulations despite current limitations in precision near first-order transitions due to mode-covering effects.
This paper provides a comprehensive, multi-method analysis (perturbative, semiclassical large-, and integrability) of the Gross-Neveu model, demonstrating that at large chemical potential, the system enters a consistent crystalline phase characterized by the condensation of bound states and the emergence of two new dynamically generated scales that govern nonperturbative effects and the oscillatory chiral condensate.
This paper proposes a Physics-Informed Neural Network framework that formulates lattice fermions as an optimization problem, successfully reconstructing the overlap fermion operator and autonomously discovering both standard and generalized Ginsparg-Wilson relations without relying on predefined approximations.
This paper introduces a score-matching diffusion model framework for sampling SU(N) lattice gauge theories, demonstrating its successful application to SU(3) configurations in two and four dimensions and showing that incorporating a Hamiltonian molecular dynamics-based corrector significantly improves sampling quality for large inverse coupling values despite increased computational cost.
This article presents the first investigation of the non-perturbative quark-gluon vertex in the complex plane within a symmetry-preserving framework, establishes a reliable analytic domain for its form factors in the soft-gluon limit, and outlines methods to extend this analysis to arbitrary momenta.
This work presents a comprehensive lattice-QCD determination of the flavor-singlet and strange axial form factors of the nucleon using CLS gauge configurations with -improved Wilson fermions, providing a complete error budget for the extrapolations with respect to chiral symmetry, the continuum limit, and infinite volume, with a specific focus on the treatment of discontinuous contributions.
Using the QCD sum rule method, this paper investigates the masses, decay widths, and dominant decay channels of the hypothetical scalar molecules () and (), predicting them to be strong-interaction unstable particles with masses of approximately 15.7 GeV and 9.7 GeV, respectively, to guide future experimental searches.
This paper demonstrates that the continuum limit of specific gauged tensor networks is well-defined, yielding a new class of states suitable for the non-perturbative study of gauge theories directly in the continuum.
This work derives pressure-energy equations of state for the nucleon from gravitational form factors and the conservation of the energy-momentum tensor, revealing a fundamental balance between pressure-induced static pressure (associated with condensate depletion and confinement) and traceless dynamic pressure, while simultaneously demonstrating that the same relations also apply to vortices in type-II superconductors and the cosmological constant in the CDM model.
