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 the Born-Oppenheimer approximation within a dynamical diquark model, this study identifies the states as compact tetraquarks composed of axial-vector diquark pairs, supported by calculated root-mean-square radii significantly smaller than 1 fm.
This paper presents state-of-the-art theoretical predictions for the electromagnetic Dirac form factors of hyperons by computing next-to-leading-order QCD corrections within the hard-collinear factorization framework and combining them with lattice QCD-determined distribution amplitudes.
This paper derives a one-loop factorization formula connecting the leading-twist QCD light-cone distribution amplitude (LCDA) to the boosted HQET LCDA of the baryon by utilizing the method-of-regions to simplify perturbative matching calculations, thereby providing a crucial step toward future lattice QCD computations of heavy baryon LCDAs.
This paper presents a lattice QCD calculation of the nucleon's gluon momentum fraction using the gradient flow method with nonperturbative renormalization, yielding a final result of 0.482(35) at 2 GeV in the MS-scheme.
This paper demonstrates that half-precision (FP16) mixed-precision linear solvers with novel rescaling steps for Lattice QCD on A64FX processors achieve practical stability with only a minor increase in iteration count compared to double-precision methods.
This paper investigates how a modified domain-wall fermion operator accelerates iterative linear solvers in lattice QCD simulations by improving convergence rates while preserving the 4D solution, supported by eigenvalue analysis and implementation within the GPU-enabled Bridge++ code framework.
This paper constructs self-dual center vortices with fractional charges from KvBLLY monopoles on with non-minimal 't Hooft flux to derive semiclassical formulas for confinement and string tensions, ultimately applying these results to evaluate Fibonacci-based twist choices for center stabilization in large- Yang-Mills theory.
This proof-of-concept study proposes that mesoscopic feedback mechanisms naturally generate infinite-range interactions in one-dimensional field theories, leading to phase transitions, spontaneous symmetry breaking, and new universality classes with significant implications for achieving room-temperature ferromagnetism in monolayer spintronics.
Using the tensor renormalization group method, this study investigates the phase structure of (3+1)-dimensional strong coupling two-color QCD at zero temperature and finite chemical potential, revealing that the critical exponents for the diquark condensate align with mean-field theory predictions.
This paper demonstrates that thermal precondensation, a phenomenon characterized by condensates forming only over finite length scales, occurs in gauge-fermion theories near the thermal chiral phase transition, becomes more pronounced with an increasing number of fermion flavors, and holds potential relevance for physics beyond the Standard Model.
