Generalized parton distributions of the nucleon based on the Faddeev approach to the NJL model Original Research Article

We study the generalized parton distributions (GPDs) using the Nambu-Jona-Lasinio (NJL) model based on the relativistic Faddeev approach. Various sum rules for the GPDs are automatically satisfied. We show the results of calculations and compare with Radyushkinʹs modellization of GPDs with the input forward parton distributions (PDs) calculated in the NJL model.
