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 presents a model-independent extraction of the nucleon axial form factor by fitting NNLO chiral perturbation theory with explicit resonance contributions to lattice QCD data, successfully describing pion-mass and momentum dependencies to yield precise physical-point values for the axial charge and radius.
This paper employs the functional renormalization group method within a linear sigma model to investigate the phase structure and anomaly effects in dense two-color QCD, revealing that while anomaly couplings for mesons are enhanced by the quark chemical potential, the topological susceptibility is suppressed at high densities and chiral partners exhibit mass degeneracy upon chiral restoration.
This paper proposes that imaginary magnetic fields induce non-Hermitian dynamics in hadronic systems, revealing the existence of exceptional points in neutral meson mass spectra that separate real and complex eigenvalue regimes and signal a field-induced deconfinement transition.
Using large-scale tensor network and exact diagonalization methods, the authors investigate an "odd" variant of the 2D Ising Fradkin-Shenker model to reveal a complex phase diagram featuring distinct valence bond solid and deconfined phases, culminating in an exotic multicritical point where confinement, Higgs condensation, and spontaneous duality symmetry breaking occur simultaneously.
This paper proposes a unified theoretical framework for dense QCD matter in the Veneziano large- limit, identifying four distinct phases—including two types of partial deconfinement driven by string or baryon condensation—and suggesting that their interplay naturally gives rise to the QCD critical point.
This paper presents a comprehensive study on tuning the anisotropic highly improved staggered quark (aHISQ) action across a wide range of renormalized anisotropies, comparing gradient flow schemes and fermion anisotropy tuning against the naive staggered action while developing an empirical model to explain the distinct behavior of taste mass splittings under anisotropy.
This paper investigates the scattering of doubly charmed baryons with light pseudoscalar mesons using chiral effective theory up to next-to-leading order, where unknown parameters are constrained by recent lattice data to predict resonance, virtual, and bound states as well as scattering observables at physical quark masses.
This paper presents a first study demonstrating that a U(1)-equivariant score-based diffusion model can effectively sample gauge link configurations for the lattice Schwinger model, yielding unbiased observables comparable to MCMC while mitigating topological freezing near critical parameters.
This paper proposes and evaluates a new formulation of the overlap Dirac operator in lattice QCD using diagonal Kenney-Laub iterates to approximate the matrix sign function, demonstrating that this approach offers superior chiral symmetry preservation and computational efficiency compared to traditional Chebyshev polynomial methods when applied to Wilson and Brillouin kernels.
This paper presents a non-perturbative lattice QCD calculation with flavors to determine the renormalization constants for the traceless components of the energy-momentum tensor, utilizing -improved Wilson actions and shifted boundary conditions to ensure the correlation functions satisfy continuum Ward identities.
