摘要：The internal structure of hadrons is important for a variety of topics, including the hadron form
factors, proton spin 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. We report on a computation of nucleon GPDs based on simulations
with two dynamical non-perturbatively improved Wilson quarks with pion masses down to
350MeV. We present results for the total angular momentum of quarks with chiral extrapolation
based on covariant baryon chiral perturbation theory.
