Generalized Parton Distributions and the structure of the constituent quark

In a scenario where the constituent quarks are composite systems, Generalized Parton Distributions (GPDs) are built from wave functions to be evaluated in a Constituent Quark Model (CQM), convoluted with the GPDs of the constituent quarks themselves. The approach permits to access the kinematical range corresponding to the DGLAP and ERBL regions, so that cross sections for deeply virtual Compton scattering could be estimated.
