Abstract

Generalized parton distributions (GPDs) provide a link between form factors, parton distributions and other observables. I discuss the connection between GPDs and parton distributions as a function of the impact parameter. Since this connection involves GPDs in the limit of vanishing skewedness parameter $\xi$ , i.e. when the off-forwardness is purely transverse, I also illustrate how to relate $\xi\neq 0$ data to $\xi=0$ data, which is important for experimental measurements of these observables.
