Abstract
The last years have seen significant advances in hadron structure calculations in lattice QCD. While extrapolations to the physical point and direct comparisons with experiment are still very challenging, lattice calculations provide already very valuable insights into a number of fundamental physics questions related to, e.g., the distribution of charge and momentum inside hadrons and the nucleon spin structure. To illustrate the recent achievements, we present and discuss latest lattice results for a small number of observables related to nucleon form factors and generalized parton distributions. We also present a study of the decomposition of the nucleon spin 1/2 in terms of quark spin and orbital angular momentum contributions. We briefly discuss results and limitations of the relevant chiral fits and extrapolations.
