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.

Nucleon axial-vector form factor and radius from radiatively-corrected antineutrino scattering data

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.

fK/fπf_K/f_{\pi} in iso-symmetric QCD and the CKM matrix unitarity

This paper presents precise lattice QCD calculations of the ratio fK/fπf_K/f_{\pi} in the iso-symmetric limit using a combined Wilson unitary and mixed-action approach, which are subsequently utilized to determine ∣Vus∣/∣Vud∣|V_{us}|/|V_{ud}| and test the unitarity of the first row of the CKM matrix after incorporating strong isospin-breaking and QED effects.

Error Correction in Lattice Quantum Electrodynamics with Quantum Reference Frames

This paper demonstrates that lattice quantum electrodynamics functions as a quantum error-correcting code by utilizing quantum reference frames to resolve syndrome degeneracy and construct explicit recovery operations for both pure-gauge and fermionic sectors, thereby revealing the deep information-theoretic significance of gauge symmetry as an encoding structure for noise protection.
