TRANSVERSE STRUCTURE OF HADRONS

Parton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, exhibit a significant deviation from axial symmetry when the target and/or quark are transversely polarized. Connections between this deformation and single-spin asymmetries as well as with quark-gluon correlations are discussed. The information content of the DVCS amplitude at fixed Q 2 can be condensed into GPDs along the 'diagonal' x = ξ plus D-form factor.
