Abstract
Results from a recent analysis of the zero-skewness generalized parton distributions (GPDs) for valence quarks are discussed. The analysis is based on a physically motivated parametrization of the GPDs with a few free parameters adjusted to the available nucleon form factor data. Various moments of the GPDs as well as their Fourier transforms, the quark densities in the impact parameter plane, are also presented. The 1 / x moments of the zero-skewness GPDs are form factors specific to Compton scattering off protons within the handbag approach. The results of the GPD analysis enable one to predict Compton scattering.
