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 exact diagonalization and matrix product state techniques on a fuzzy sphere to extract conformal data for the -dimensional Wilson-Fisher CFT, identifying 32 primary operators and verifying their scaling dimensions against conformal bootstrap predictions and large charge expansion results.
This paper employs a nonrelativistic quark-diquark model to predict the mass spectra, magnetic moments, and Regge trajectories of the triply heavy and baryons, establishing a consistent link to experimental meson data and providing reliable theoretical benchmarks for future searches at LHCb.
This paper presents an update from the BMW Collaboration on their ongoing calculation of isospin-breaking effects in the pion decay constant using staggered quarks with near-physical pion masses and QED, including preliminary results for the axial-pseudoscalar correlator and future plans.
This lattice QCD study at the flavour symmetric point reveals attractive interactions and multiple pole singularities in the flavour-exotic sector, identifying partners of the experimentally observed and states, while finding only weak interactions without poles in the sector.
This paper presents continuum-extrapolated lattice simulations of hot QCD at the physical point using the complex Langevin equation to determine the equation of state at unprecedentedly high baryon densities, demonstrating controlled convergence and agreement with previous lattice and perturbative results.
This paper provides numerical evidence from a partially reduced twisted Eguchi-Kawai model that the confined phase of large- gauge theory with one adjoint Dirac fermion persists under spatial compactification with periodic boundary conditions, supporting an adiabatic continuity scenario between large and small circles, whereas antiperiodic boundary conditions induce a clear deconfinement transition.
This paper demonstrates that an emergent, non-invertible gauge symmetry arises within specific sectors of a fragmented dipole-conserving spin chain, enabling the exact quantum simulation of a gauge theory using a non-gauge-invariant Hamiltonian.
This paper investigates rare dileptonic decays of , , and baryons within the Type III Two-Higgs-Doublet Model, calculating key observables like branching ratios and forward-backward asymmetries using light-cone QCD form factors to compare predictions against Standard Model results and assess the model's viability for future experimental verification at LHCb and Belle II.
Using a non-relativistic quark model with a harmonic oscillator potential, this paper investigates how neutral and charged mesons behave in magnetic fields across weak to strong regimes, highlighting distinct differences in their transverse dynamics and demonstrating how zero-point energy stabilizes high-spin charged mesons by canceling orbital Zeeman effects.
This paper outlines the current modernization efforts of the International Lattice Data Grid (ILDG), detailing recent advancements in metadata and middleware services tailored for large collaborations, as well as future development plans.
