Generalized parton distributions of the nucleon using the NJL model based on the Faddeev approach

We study the generalized parton distributions (GPDs) using the Nambu-Jona-Lasinio (NJL) model based on the relativistic Faddeev approach. Pauli-Villars regularization scheme, which conserves gauge invariance, is used, such that various sum rules for the GPDs and parton distributions are automatically satisfied. We present the results of calculations and compare with Radyushkin's modellization of GPDs.
