摘要:First lattice results on moments of the tensor GPDs are presented. These quantities are highly
relevant for the nucleon spin structure as they describe the correlation between quark spin, nucleon
spin and quark orbital angular momentum. The Soffer bound is shown to be nearly saturated for
the up and down quarks in a proton.
