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 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.
This study presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using boosted correlators in the Coulomb gauge, demonstrating that the method yields results compatible with global analyses for valence-quark distributions while highlighting the need to address excited-state contamination in full-quark-channel extractions.
This paper demonstrates that resonant pair-production terms in a lattice gauge theory enable the formation of stable, high-energy "repulsively bound" hadrons through a novel dynamical mechanism, a finding supported by matrix product state simulations and an effective model that suggests experimental realization on modern quantum hardware.
This paper demonstrates that Gaussian Process Regression provides a robust, non-parametric Bayesian framework for reconstructing parton distribution functions from lattice QCD data, offering controlled uncertainty estimates and reduced model bias compared to traditional functional forms.
Using lattice QCD to study coupled-channel scattering, the authors find that interactions are weak near threshold and show no evidence of bound states or resonances between the state and the threshold.
Using the QCD sum rule method, this paper investigates the properties of two heavy-quark hadronic molecules, and , predicting their masses and relatively broad decay widths to demonstrate their instability against dissociation.
The paper introduces a new topological observable called "simplicity," based on the Betti numbers of Abelian monopole current loops in SU(3) Yang-Mills theory, which provides a more accurate determination of the deconfinement temperature and serves as a potential new order parameter for studying the phase structure of QCD.
