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 practical Hamiltonian approach for simulating SU(2) gauge theory with staggered fermions on a semi-simple cubic lattice, a qubit-efficient 3D structure that simplifies Gauss's law handling while preserving the ability to define local fermion derivatives for near-term quantum computers.
This paper employs numerical minimization of the lattice action in trace-deformed Yang-Mills theory on a twisted to demonstrate how fractional instantons, monopole-instantons, and center vortices morph into one another as geometric parameters vary, revealing that the analytic picture of flux collimation holds in pure Yang-Mills theory under specific shape conditions and that transitions between configurations can be discontinuous.
By applying state-of-the-art theoretical tools and empirically mitigating lattice artifacts to reanalyze existing large-momentum lattice QCD datasets, this study demonstrates that the proton's isovector parton distribution function is consistent with experimental global fits within approximately one standard deviation, validating the predictive capability of the large-momentum expansion approach.
This paper investigates multi-particle states in the (1+1)d Ising model by combining the tensor renormalization group method with transfer matrix spectroscopy and impurity tensor networks to identify quantum numbers, extract one- to three-particle energy levels, and validate two-particle scattering phase shifts and three-particle degeneracies against theoretical predictions.
This paper presents a quantum algorithm utilizing Wilson fermions to simulate Generalized Parton Distributions in the Schwinger model, ensuring charge conjugation symmetry while demonstrating polynomial resource scaling and validating results through exact diagonalization.
This paper demonstrates that a purely lattice duality defect in a Majorana representation of the transverse-field Ising chain induces an emergent Andreev-like boundary condition by implementing a chiral fermion-parity flip, thereby providing a microscopic realization of the Emery–Kivelson boundary, Maldacena–Ludwig monopole scattering, and an axial -symmetric charge-flip interface.
This paper investigates the semileptonic and nonleptonic weak decays of bottom baryons and using three-point QCD sum rules to calculate form factors, decay widths, and branching ratios, thereby providing theoretical predictions to test Standard Model validity and explore new physics in heavy baryonic systems.
Using the tensor renormalization group method, this study investigates the phase structure of (3+1)-dimensional cold and dense QCD in the strong coupling limit, determining consistent critical quark masses where first-order chiral and nuclear transitions terminate and confirming these findings against dual formulation Monte Carlo simulations and mean-field analysis.
This paper establishes a framework for transforming between smeared spectral functions using different kernels by deriving conditions for exact analytic conversions and providing regulated maps with computable systematic error bounds when exact transformations are unavailable.
This paper proposes a theoretically grounded method for extracting charmonium branching fractions from radiative decays that resolves tensions between experimental data and theoretical predictions by eliminating the need for empirical damping functions in photon line shape analysis.
