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.

InflationEasy is a C++ lattice code that extends the capabilities of LATTICEEASY to simulate nonlinear scalar field dynamics in an expanding universe, enabling fully nonperturbative studies of inflationary regimes, primordial black hole formation, and scalar-induced gravitational waves through features like a nonperturbative method.
This paper presents an exact solution for a -dimensional Polyakov loop model with an exact static quark determinant in the 't Hooft-Veneziano limit, demonstrating that the system reduces to a solvable deformed unitary matrix model whose phase diagram and transition types depend explicitly on the quark flavor-to-color ratio .
This paper demonstrates that 3D quantum dimer models with staggered matter exhibit geometric fragmentation and anomalous thermalization under external electric fields, where flux polarization and Gauss Law constraints trap excitations in 2D planes to create exponentially many athermal fragments, including sectors hosting immobile fractonic excitations.
This paper proposes a quark-meson framework incorporating temperature-dependent quark masses and anomalous magnetic moments to reconcile lattice QCD magnetic susceptibility data with theoretical models, demonstrating that quark degrees of freedom must emerge significantly below the QCD cross-over temperature (around 120 MeV) to explain the observed paramagnetism.
This paper presents non-perturbative lattice calculations of the low-lying spectrum and matrix elements of chimera baryons within a Sp(4) gauge theory, a key component of composite Higgs models, utilizing both quenched and dynamical fermion approximations.
This paper reviews the Fermilab Lattice and MILC collaborations' efforts to perform a correlated lattice QCD analysis using Highly Improved Staggered Quarks and Staggered Chiral Perturbation Theory to precisely determine the CKM matrix elements and without nuclear inputs, thereby testing the first-row unitarity of the CKM matrix and probing physics beyond the Standard Model.
This paper presents a constituent two-gluon model for the lowest-lying glueball states in pure Yang-Mills theory, calibrated against lattice results, which reveals that the compact scalar glueball has a radius comparable to the instanton size while the extended tensor state is shaped by a centrifugal barrier, with the framework also supporting Regge behavior for excited states.
This paper introduces three key improvements to the orbifold lattice approach for simulating SU(2) gauge theories on quantum computers—specifically new simplified Hamiltonians, a more qubit-efficient encoding, and a modified Hamiltonian term that reduces scalar mass requirements—thereby significantly lowering circuit depth and qubit needs while validating the efficacy of non-compact variables through (2+1)D Monte Carlo benchmarks.
This paper presents new, high-precision determinations of the masses for the , , and quarks using lattice QCD simulations with HISQ discretization and QED corrections, achieving some of the most accurate values to date while providing a detailed analysis of discretization errors and isospin corrections.
This paper demonstrates that the tensor renormalization group (TRG) method, when applied to symmetry-twisted partition functions, provides an efficient framework for detecting spontaneous symmetry breaking and accurately determining critical temperatures and exponents in the 2D Ising, 3D , and 2D (BKT) models.
