The structure of the nucleon from lattice QCD simulations — •Philipp Hägler for the QCDSF-UKQCD and LHPC collaboration — Institut für Theoretische Physik T39, Physik-Department der TU München, D-85747 Garching

Generalized and transverse momentum dependent parton distribution functions encode a wealth of information about the internal structure of hadrons. They provide direct access to correlations of spin, momentum and coordinate degrees of freedom, and in particular the orbital angular momentum and the spatial distribution of quarks in the nucleon. In this talk, I give an overview of recent lattice QCD results for these observables, based on simulations performed by the QCDSF/UKQCD and LHPC collaborations. Whenever feasible, the lattice results are extrapolated to the physical limit using baryon chiral perturbation theory.
