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 expands on previous findings by investigating the topological structure of the entanglement radius in (2+1)D Yang-Mills theory, specifically examining how flux tube entanglement entropy behaves when the entangling region's cross-sectional length is comparable to the flux tube's intrinsic thickness.
This paper applies a Pauli-Villars regulated photon propagator defined in continuum infinite volume to lattice QCD calculations on CLS ensembles to determine the electromagnetic pion mass splitting, thereby avoiding power-law finite-size effects and enabling direct cross-checks with phenomenology.
This paper presents an efficient implementation of the Quantum Minimally Entangled Typical Thermal States (QMETTS) algorithm for gauge theories at finite temperature and density, featuring derived measurement bases to preserve gauge invariance, a noise-robust sampling method for expectation values, and numerical validation on a (1+1)-dimensional model.
This paper conjectures a lower bound for the critical exponent in continuous phase transitions described by Landau-Ginzburg-Wilson theories, proposing the inequality (which implies for unitary theories) based on the condition , a hypothesis supported by arguments from lattice models, -expansions, and exact two-dimensional conformal field theory results.
This paper proposes a string field theory for branched polymers with loops coupled to the critical Ising model, demonstrating that its non-perturbative partition function satisfies a third-order linear differential equation and a Wheeler-DeWitt equation derived via both matrix model loop equations and stochastic quantization.
This paper presents a study of the mass spectra and mass differences of heavy hadrons containing bottom quarks using MILC's 2+1+1 flavor HISQ gauge ensembles, employing a mixed-action approach with NRQCD for bottom quarks, anisotropic Clover for charm, and O(a)-improved Wilson-Clover for light and strange quarks.
This paper presents a non-perturbative determination of the QCD Equation of State for three massless quark flavors across a temperature range from 3 GeV to the electroweak scale, revealing that even at these extreme temperatures, perturbative predictions remain insufficient without incorporating non-perturbative contributions.
This paper proposes and numerically verifies a lattice formulation of the -valued Arf-Brown-Kervaire invariant for Majorana fermions on two-dimensional non-oriented manifolds, demonstrating that it can be extracted from Pfaffians of the Wilson Dirac operator and agrees with continuum theory results.
Using a unified chiral effective field theory framework calibrated with lattice QCD data, this study predicts repulsive interactions for the system while identifying strong attractive forces in the system that support bound states, with significant mass splitting between channels driven by two-pion exchange spin-spin terms.
This paper presents a first-principles lattice QCD calculation of the proton-proton fusion matrix element at an unphysical pion mass, demonstrating the feasibility of the approach while highlighting that large uncertainties in two-nucleon scattering parameters currently limit the precision of the extracted low-energy constant .
