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 utilizes QCD light-cone sum rules to calculate the electromagnetic multipole moments of -type strange hidden-charm pentaquarks, revealing distinct magnetic dipole, electric quadrupole, and magnetic octupole signatures that depend on diquark structure and provide key discriminants to differentiate between compact pentaquark and molecular interpretations.
This paper utilizes Born-Oppenheimer effective field theory (BOEFT) to systematically quantify open-flavor threshold effects on the quarkonium spectrum by solving coupled Schrödinger equations with lattice-constrained static potentials, successfully reproducing experimental data and providing a field-theoretical interpretation of the phenomenological model's pair-creation constant.
This paper demonstrates that generalized symmetries, including higher-form, subsystem, gauge, and non-invertible symmetries, can induce exponential Hilbert space fragmentation, thereby challenging the assumption that such fragmentation necessarily implies ergodicity breaking and revealing its role in disorder-free localization.
This paper demonstrates that chiral-odd dimeson generalized distribution amplitudes, which encode the spin-orbit correlation in spin-zero mesons, can be experimentally accessed in reactions through the interference between leading one-photon and two-photon exchange amplitudes, offering a direct path to probe this previously unmeasured sector of meson structure at facilities like BES III.
This study employs Matrix Product States to investigate fermion discretization effects in the two-flavor lattice Schwinger model, demonstrating that twisted mass fermions offer superior convergence to the continuum limit and reduced finite-volume dependence compared to staggered and Wilson formulations, thereby validating their potential for future Hamiltonian simulations of higher-dimensional gauge theories.
This paper provides a rigorous proof that generalized Ising models with interaction parameter exhibit "entropic order" at arbitrarily high temperatures and solve NP-hard graph packing problems, leading to the emergence of a novel "entropic glass" phase on arbitrary graphs.
This paper presents a brief biography of William A. Bardeen (1941–2025), an American theoretical physicist at Fermilab renowned for his foundational contributions to the chiral anomaly, quantum chromodynamics, dynamical electroweak symmetry breaking, and heavy-light quark bound states.
This paper introduces a multiscale generative sampler that combines conditional Gaussian mixture models and masked continuous normalizing flows to overcome critical slowing down in lattice field theories, achieving significantly reduced autocorrelation times and enabling unbiased Multilevel Monte Carlo variance reduction for the two-dimensional scalar theory near criticality.
This paper compares the pion decay width in a uniform magnetic field calculated via chiral perturbation theory with lattice QCD results, finding consistency at large magnetic fields while attributing discrepancies at weak fields to differences in pion decay constants.
This paper utilizes QCD sum rule methods to model the resonance as a all-charm tetraquark in a diquark-antidiquark configuration, calculating its mass and decay widths to demonstrate consistency with experimental data and support its interpretation as a tensor state.
