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 reviews various theoretical and computational approaches—such as holomorphic extensions, dual variables, and machine learning—aimed at overcoming the sign problem in lattice field theories to better understand the QCD phase diagram and real-time dynamics.
The paper uses D-brane configurations to study the moduli space of fractional instantons on a twisted four-torus, demonstrating that this space is locally equivalent to the Higgs branch of an supersymmetric theory with a manifest hyper-Kähler structure.
This paper presents lattice QCD results for the inclusive semileptonic decay rate, providing a high-precision calculation with few-percent error that aligns with current experimental data through rigorous chiral and continuum extrapolations.
This paper calculates second- and fourth-order conserved-charge fluctuations in -flavor QCD using Möbius domain-wall fermions to study quark number susceptibilities across different quark masses and temperatures, comparing the results to hadron resonance gas models and Stefan–Boltzmann limits.
This paper benchmarks the performance of various variational quantum ansätze in simulating the Transverse Field Ising Model across one, two, and three dimensions with up to 27 spins, evaluating their expressivity and optimization capabilities in capturing ground state properties like entanglement entropy and critical phenomena.
This paper presents the first complete next-to-leading order QCD calculation for fully charm tetraquark production at hadronic collisions, incorporating gluon radiation effects through resummation and utilizing LHCb and CMS data to extract universal long-distance matrix elements and predict kinematic distributions for the and its spin-zero partners.
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.
