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 investigates a four-dimensional lattice tensor gauge theory coupled to bosonic matter using Monte Carlo simulations, revealing that while the weak coupling phase is destroyed by instanton proliferation in the pure gauge limit, distinct phases emerge for different charge values, including a single phase with a critical endpoint for and a Higgs phase recovering fractonic topological order for .
This paper reviews the current status of the muon anomalous magnetic moment as a probe for physics beyond the Standard Model following the final FNAL results and the second Theory Initiative White Paper, while discussing experimental achievements, ongoing efforts to improve theoretical predictions, and future prospects for surpassing current precision limits.
This paper utilizes thermofield dynamics and the correspondence between low-energy excitations and Fisher zeros to analyze the quantum XY chain, revealing that "giant bubbles" of Fisher zeros near the gapless XX limit provide a characteristic energy scale that contradicts standard Luttinger liquid theory and links spectral weight transfer to unconventional gap behaviors.
This paper proposes a Variational Quantum Eigensolver (VQE) approach that improves ground state accuracy by replacing hard-coded orthogonality constraints with soft-coded penalty terms, enabling shallower quantum circuits while maintaining high fidelity across benchmark spin-glass models.
Using staggered fermions on the lattice, the study demonstrates that localized low-lying Dirac eigenmodes emerge in QCD at a temperature () between 155 and 158 MeV, which aligns precisely with the pseudocritical crossover temperature determined by chiral condensate and light-quark susceptibility.
By solving coupled Dyson-Schwinger equations for quark and gluon propagators, this study determines a critical flavor number of for chiral symmetry restoration in QCD and characterizes the associated second-order phase transition with a critical exponent of approximately 0.53.
This paper presents a precise lattice-QCD determination of the transition form factors using physical quark masses to calculate semileptonic decay rates, test lepton-flavor universality, and extract the CKM matrix element by combining theoretical results with experimental data from BESIII and LHCb.
This paper utilizes gauge/string duality to investigate string breaking in spatial Wilson loops, specifically analyzing the influence of light flavors on the pseudopotential and estimating the spatial string breaking distance for $SU(3)$ gauge theory across temperatures from 0 to .
This paper proposes a method to locate the QCD critical point by analyzing contours of constant entropy density extrapolated from zero net-baryon density, yielding a predicted critical point at MeV and MeV based on Wuppertal–Budapest lattice QCD data.
This high-statistics lattice QCD study at a heavy pion mass ( MeV) demonstrates that di-nucleons do not form bound states, attributing previous claims of deeply bound states to misidentifications of the spectrum arising from off-diagonal correlation function elements rather than physical hexaquark states.
