“…In Ref. [32], proton and neutron electromagnetic form factors G E, M (Q 2 ) up to 8 GeV 2 were calculated with a range of lattice spacings as well as quark masses that approach the physical point. The initial resulting form factors seem to overestimate the ones from experiment by a large factor, but their ratios are in much better agreement with experiment and phenomenology.…”

We review the latest progress in lattice QCD calculations of the hadron structure. There have been improved calculations of form factors and gravitational form factors by removing the lattice artifacts. Additionally, we highlight the rapid development in lattice calculations of x-dependent parton distributions. This area of study has expanded from various one-dimensional parton distribution functions (PDFs) to three-dimensional distributions like generalized parton distribution functions (GPDs) and transverse-momentum-dependent PDFs (TMDs). These advancements are being achieved within the large momentum effective theory (LaMET) framework and similar methodologies, with considerable progress in controlling lattice artifacts as well as enhancing theoretical accuracy.
