Hadron structure in lattice QCD and ChPT — •Philipp Hägler — Institut für Theoretische Physik T39, Physik-Department der TU München, James-Franck-Strasse, D-85747 Garching

This talk summarizes recent results from hadron structure calculations in lattice QCD. Substantial progress has been made in particular with respect to nucleon form factors and moments of (generalized) parton distributions. These observables allow us to investigate a number of fundamental physics questions related to, e.g., the distribution of charge and momentum in hadrons and their internal spin structure. Results from chiral perturbation theory required for the extrapolation of the lattice data to the physical point will be briefly discussed and applied to selected hadron structure observables.
