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.

Using four-dimensional causal dynamical triangulation simulations, this paper presents evidence for the existence of massive geons—self-bound graviton states—through curvature-curvature correlators, suggesting potential implications for dark matter and primordial black holes while noting a connection between their mass and the expansion phase of the de Sitter universe.
This paper extends the RI/SMOM renormalization scheme to semi-leptonic operators by utilizing chirally symmetric massless QCD to relate them to protected vector currents, demonstrating the equivalence of a new family of projectors with recent results relevant for calculating Wilson coefficients.
This paper proposes a feasible scheme using ultracold atoms in a periodically driven 3D optical Raman lattice to realize unpaired Weyl points with tunable net chirality, thereby enabling the observation of the chiral magnetic effect and providing a controllable platform for exploring nonequilibrium topological phenomena.
This paper proposes a photonic analog quantum simulation scheme based on the Jaynes-Cummings-Hubbard model to replicate the real-time dynamics of a (1+1)-dimensional Lattice Gauge Theory with dynamical matter by mapping polaritonic hopping in cavity arrays onto a spin-1/2 Quantum Link Model.
This paper analyzes lattice QCD data using unitarized chiral perturbation theory to reveal that the experimental resonance corresponds to a two-pole structure, where a lower pole () behaves like the meson and an upper pole relates to the representation, with their distinct behaviors across chiral trajectories offering new insights into their underlying quark-gluon dynamics.
This paper presents a comprehensive finite-volume calculation of pion-pion scattering within Chiral Perturbation Theory and the Inverse Amplitude Method that incorporates discretization effects across all scattering channels and group representations, revealing significant corrections for small volumes () that improve the accuracy of energy level and phase-shift determinations compared to previous analyses.
This lattice simulation study reveals that weak acceleration in gluodynamics transforms the finite-temperature confinement-deconfinement phase transition into a spatial crossover where coexisting phases are separated by a boundary accurately described by the Tolman-Ehrenfest law, suggesting such spatial transitions may occur near Schwarzschild black hole horizons.
Motivated by future Electron-Ion Collider physics, this paper demonstrates that kinematically enhanced interpolators significantly improve the precision of renormalized nucleon matrix elements at high momenta while showing no dependence on lattice spacing, thereby establishing them as a promising standard for modern lattice QCD parton physics calculations.
This paper presents the first non-perturbative lattice determination of bubble nucleation rates seeded by topological defects in a cubic anisotropy model, demonstrating excellent agreement with semi-classical predictions that include fluctuation determinants away from spherical symmetry.
The CJ26 global QCD analysis presents a new set of NLO parton distribution functions by incorporating the complete suite of JLab 6 GeV and the first published 12 GeV data to uniquely disentangle higher-twist effects from off-shell nucleon corrections, thereby significantly reducing uncertainties in the large- structure function and valence quark ratios.
