Spin Structure of Nucleons Wolf-Dieter Nowak (Desy, Germany)
Recent data on the longitudinal and transverse spin structure of
nucleons will be discussed, as obtained by experiments studying polarized
nucleons at CERN, DESY, JLab, and RHIC. In particular the spin structure
functions g1 and b1 will be shown, and current results on sea and gluon
distribution functions will be mentioned. SIDIS transverse asymmetries
and conclusions on the extraction of Sivers and Collins functions will
be given. Different asymmetries measured in Deeply Virtual Compton
Scattering will be presented, together with conclusions and outlook
towards accessing Generalized Parton Distributions. Also, access to
parton orbital and total angular momentum will be mentioned.
