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.
Below are the latest papers in High Energy Physics – Lattice, curated directly from arXiv and ready for you to explore.
This paper utilizes the density of states method in lattice field theory to characterize the first-order confinement/deconfinement phase transition in finite-temperature Yang-Mills theory, demonstrating the persistence of non-perturbative phenomena and establishing critical parameters for future continuum limit extrapolations relevant to gravitational wave predictions.
This paper employs QCD sum rules to investigate the masses of purely top-quark bound states, finding that the calculated pseudoscalar toponium mass aligns with recent CMS and ATLAS observations near the threshold while also providing theoretical predictions for the vector toponium and triply-top baryon to guide future high-energy collider experiments.
This paper presents the first sub-percent precision lattice QCD calculation of the next-to-leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment, yielding a result that is twice as precise as the 2025 White Paper estimate and exhibits a 4.6 tension with data-driven evaluations based on pre-CMD-3 hadronic cross-section measurements.
This paper investigates the quantum Ising model on (2+1)-dimensional anti-de Sitter space using tensor networks to map its phase diagram, characterize boundary correlation scaling and entanglement entropy consistent with holography, and analyze scrambling behavior via out-of-time-ordered correlators.
This paper applies radiative corrections to recent MINERvA antineutrino-hydrogen scattering data to extract the nucleon axial-vector form factor and radius, thereby enabling more precise comparisons with lattice QCD predictions and reducing uncertainties in neutrino interaction modeling.
This paper investigates the pole structure of the resonance by computing baryon-meson energy levels on -symmetric lattice QCD ensembles using distillation techniques, aiming to provide input for chiral perturbation theory to resolve the debate over its two-pole nature.
This paper presents a symmetry-preserving approximation for computing light meson spectra that incorporates fully-dressed quark-gluon vertices and demonstrates significantly improved agreement with experimental masses compared to the traditional rainbow-ladder approximation.
This paper challenges established views on hot QCD by demonstrating that an intermediate phase exhibits emergent chiral spin symmetry with persistent mesonic excitations, and proposes that thermal quantum field theories are fundamentally composed of non-perturbative "thermoparticles" rather than perturbative degrees of freedom.
This paper presents precise lattice QCD calculations of the ratio in the iso-symmetric limit using a combined Wilson unitary and mixed-action approach, which are subsequently utilized to determine and test the unitarity of the first row of the CKM matrix after incorporating strong isospin-breaking and QED effects.
This paper presents Causal Dynamical Triangulations (CDT) as a nonperturbative lattice approach to quantum gravity that successfully demonstrates the dynamical emergence of a classical de Sitter-like universe from a sum over causal triangulations, while revealing unique short-scale properties such as a spectral dimension of approximately 2 and evidence for an ultraviolet fixed point.
