Abstract

The physical interpretation of generalized parton distributions (in the limit ξ = 0) as Fourier transforms of impact parameter dependent parton distributions is discussed. Particular emphasis is put on the role of the target polarization. For transversely polarized targets, we expect a significant deviation from axial symmetry for the distribution in the transverse plane. We conjecture that this transverse distortion, in combination with the final state, provides a natural explanation for the sign of the Sivers contribution to semi-inclusive single-spin asymmetries.
