Lattice QCD studies of nucleon structure — •Philipp Hägler — Institut für Theoretische Physik T39, TU München, Garching, Germany
Generalized as well as intrinsic transverse momentum dependent parton distributions (GPDs and TMDs) are the essential, non-perturbative ingredients in the description and interpretation of, e.g., semi-inclusive deep inelastic and deeply virtual Compton scattering experiments at HERA, COMPASS and JLab. They provide a wealth of information about the internal quark and gluon structure of hadrons, giving for example direct access to the nucleon spin sum rule, the spatial distribution of partons in the transverse plane, and remarkable correlations between intrinsic transverse momentum and spin degrees of freedom. In this talk, I will give an overview of corresponding results from dynamical lattice QCD calculations, thereby illustrating the substantial progress that has been made in the recent years in lattice studies of hadron structure.
