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 an effective theory of center vortices to demonstrate the area law fall-off and derive the string tension for SU(2) gauge theory in three-dimensional Euclidean space-time, revealing that the repulsive force between vortices increases with temperature to facilitate the deconfinement regime.
This paper proposes configurational temperature, a diagnostic tool derived from action gradients and Hessians, as a highly sensitive method for detecting algorithmic errors and ensuring correct Boltzmann sampling in Complex Langevin simulations, thereby addressing a critical limitation of existing drift-based diagnostics.
This paper investigates the impact of a novel flavor-mixing interaction arising from vacuum polarization on the parton distribution functions of charged kaons and pions within the U(3) Nambu--Jona-Lasinio model, demonstrating that these mixing effects, which are proportional to quark effective mass differences, significantly improve the agreement of theoretical predictions with experimental data at specific momentum fractions.
This paper improves the analysis of quark confinement in the proton by incorporating light-cone QCD sum rules and formulating the quark force reconstruction as a regularized inverse problem, yielding a less model-dependent determination that remains consistent with a linear QCD potential.
Using QCD sum rules at finite temperature and density, this study reveals that while the in-medium masses of and multiplets remain remarkably stable with only minor shifts, their decay constants are highly sensitive to the medium, exhibiting significant particle-antiparticle asymmetry driven by baryon density that provides a theoretical foundation for future heavy-ion collision experiments.
This review argues that the unquenched theoretical framework, which incorporates coupled-channel effects and hadronic loops, is essential for resolving long-standing discrepancies in charmonium spectroscopy and explaining the emergence of exotic hadronic states that cannot be accounted for by traditional quenched potential models.
This paper presents a lattice QCD calculation of nucleon unpolarized second Mellin moments using four physical-mass ensembles to determine the continuum-limit contributions of quarks and gluons to the proton's momentum, angular momentum, and orbital angular momentum.
Revisiting short-range baryon-baryon potentials within the constituent quark model, this study predicts that specific flavor antidecuplet states and the system possess sufficient attraction to form dibaryon bound states as hadronic molecules, while also comparing these findings with lattice QCD simulations.
This paper demonstrates that specific new physics scenarios, such as a model with large complex phases and right-handed couplings, can simultaneously enhance the branching ratios of , , and while resolving the anomaly, all without conflicting with the recent NA62 measurement of or the constraint.
This paper derives an analytical solution for the heavy quark mass dependence of the baryon's light-cone distribution amplitude by solving a first-order differential equation within a factorization framework that incorporates renormalon corrections, thereby providing a crucial tool for extrapolating lattice QCD results to the physical bottom quark mass.
