摘要：

We study generalized parton distributions in the impact parameter representation, including the case of nonzero skewness. Using Lorentz invariance, and expressing parton distributions in terms of impact parameter dependent wave functions, we investigate in which way they simultaneously describe longitudinal and transverse structure of a fast moving hadron. We compare this information with the one in elastic form factors, in ordinary and in k(T)-dependent parton distributions.
