Moments of generalized parton distributions and quark angular momentum of the nucleon

Presenter: Munehisa Ohtani — Regensburg university

QCDSF collaboration

The internal structure of hadrons is important for a variety of topics, including non-perturbative effects on the hadron form factors, proton spin contents and spin asymmetry in polarized proton scattering. For a systematic study generalized parton distributions (GPDs) encode important information on hadron structure in the entire impact parameter space. In this talk, we report on nucleon GPDs based on simulations with two dynamical non-perturbatively improved Wilson quarks with pion masses down to 300 MeV. We present results for the total angular momentum of quarks.
