摘要:Generalized parton distributions encompass a wealth of information concerning the threedimensional
quark and gluon structure of the nucleon, and thus provide an ideal focus for the
study of hadron structure using lattice QCD. The special limits corresponding to form factors and
parton distributions are well explored experimentally, providing clear tests of lattice calculations,
and the lack of experimental data for more general cases provides opportunities for genuine predictions
and for guiding experiment. We present results from hybrid calculations with improved
staggered (Asqtad) sea quarks and domain wall valence quarks at pion masses down to 350 MeV.
