Generalized parton distributions can be used to obtain information about the dependence of parton distributions on the impact parameter. Potential consequences for T -odd single-spin asymmetries are discussed.

On the basis of requirements of unitarity and analyticity we analyze the real and imaginary parts of the scattering amplitude at recent ultrahigh energies, [Formula: see text]. The predictions for the region [Formula: see text] and [Formula: see text] are given supposing the black disk asymptotic regime. It turns out that the real part of the amplitude is concentrated in the impact parameter space at the border of the black disk.
