Scientific paper

Generalized parton distributions (GPDs) have become a standard QCD tool for analyzing and parametrizing the non perturbative parton structure of hadron targets. GPDs might be viewed as non-diagonal overlaps of light-cone wave functions and offer the opportunity to study the partonic content of the nucleon from a new perspective, allowing one to study the interplay between longitudinal and transverse partonic degrees of freedom. In particular, we will review some of the new information encoded in the GPDs through the definition of impact-parameter dependent parton distributions and form factors of the energy-momentum tensor, by exploiting different dynamical models for the nucleon state.
