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 proposes a lattice-ready entanglement observable, the vacuum-subtracted radius flow of Rényi entropy, to extract hadronic gravitational form factors by fitting flow data to a basis of spin-0 and spin-2 templates, thereby enabling the discrimination of scalar versus spin-2 entanglement control through the location and characteristics of the flow's extremum.
This paper presents the latest hybrid determination of the hadronic vacuum polarisation contribution to the muon magnetic moment by the BMW and DMZ collaborations, achieving 0.45% precision and overturning the theoretical consensus to resolve the long-standing discrepancy with experimental measurements.
Using QCD sum rules, this study interprets the resonance as an -wave molecular pentaquark state and calculates its mass and decay properties, finding results consistent with experimental data.
This study demonstrates that including a dynamical charm quark and utilizing a mixed action setup yield light hadron properties consistent with standard 2+1 flavor calculations, with the mixed action's discretization errors potentially canceling out to improve continuum extrapolation convergence.
This paper introduces a novel quantum error mitigation scheme for NISQ devices that utilizes a polynomial subset of extended BBGKY hierarchy equations as a sampling criterion to effectively recover real-time chiral dynamics in the Schwinger model with polynomial resource overhead.
This paper presents optimized quantum simulation algorithms for scalar field theories using finite volume approaches and various fault-tolerant techniques, demonstrating that physically meaningful scattering process simulations are feasible with approximately 4 million physical qubits and T-gates, placing them within the reach of near-term quantum hardware capabilities comparable to leading chemistry simulations.
This review examines the fundamental principles of thermal field theory in a background magnetic field, focusing on equilibrium systems to analyze bulk thermodynamic properties and real-time observables relevant to the thermo-magnetic QCD plasma in heavy-ion collisions.
This paper defends Large-Momentum Effective Theory (LaMET) against recent claims that it suffers from an unquantifiable inverse problem, arguing that physics-guided systematic extrapolation remains the most reliable method for estimating uncertainties in parton distribution calculations even when lattice data precision is suboptimal.
This paper reviews how recent advancements in Large Momentum Effective Theory (LaMET), including improved renormalization schemes, higher-order matching kernels, and novel lattice operators, are enhancing the precision and reliability of first-principles lattice QCD calculations for proton parton distributions.
This paper demonstrates that the Wilson formulation of fermions in lattice gauge theory unifies the description of chiral anomalies by showing how the discrete Dirac operator's eigenvalue structure, specifically the collision of complex pairs outside the perturbative region, facilitates transitions between topological sectors.
