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 the bound state of the + system by deriving a folding - potential from the HAL QCD - interaction, demonstrating that it fits a Woods-Saxon function and yields binding energies consistent with previous findings, while further validating the methodology through a comparative analysis of the - system.
This paper utilizes Light Cone Sum Rules with twist-6 contributions to calculate the branching fraction of the decay, thereby determining the allowed mass range for the dark antibaryon consistent with -mesogenesis constraints from BaBar and Belle experimental data.
This paper presents a precise continuum-limit lattice QCD calculation of heavy meson HQET light-cone distribution amplitudes, achieving a threefold reduction in uncertainty for key inverse moments to significantly improve the theoretical precision of decay predictions and resolve long-standing bottlenecks in flavor physics.
This paper bridges a gap in the study of the 3D dipolar universality class by introducing a constrained lattice model and a hybrid Monte Carlo algorithm to simulate systems up to , thereby confirming a continuous phase transition and providing new estimates for critical exponents and the Binder ratio.
This paper compares isospin-symmetric lattice QCD calculations of hadronic vacuum polarization with dispersive results derived from corrected hadronic -decay data, finding generally good agreement overall but revealing significant discrepancies in the four-pion mode when evaluated against expectations from Pais relations and cross sections.
Using Faddeev equations in configuration space, this study demonstrates that the large binding energy of the system arises from the short-range behavior of strong attractive potentials, while revealing that the Coulomb interaction has only a marginal perturbative effect on the system's spatial configuration and binding energy.
This paper establishes the specific conditions on gauge group colors and fermion family multiplicities required for generalized chiral gauge theories with fundamental or adjoint scalars to achieve complete asymptotic freedom across all gauge, Yukawa, and quartic couplings.
This paper introduces a gauge-fixing-free truncation method for loopy tensor networks that identifies and removes redundant bond dimensions by analyzing zero modes of the metric tensor, demonstrating its effectiveness in optimizing the purification of the two-dimensional finite-temperature lattice gauge theory using iPEPS.
This paper investigates several simple asymptotically-free chiral gauge theories to reveal surprisingly rich infrared effective structures, RG flows, and light spectra by applying recent developments in generalized symmetries and anomaly matching alongside established knowledge of vectorlike theories.
This study demonstrates that the Worldvolume Hybrid Monte Carlo method effectively mitigates the severe numerical sign problem in the two-dimensional Hubbard model away from half-filling, successfully computing physical observables on and lattices where standard determinant quantum Monte Carlo methods fail.
