Generalized parton distributions and Deeply Virtual Compton Scattering in Color Glass Condensate model

Abstract

Within the framework of the Color Glass Condensate model, we evaluate quark and gluon Generalized Parton Distributions (GPDs) and the cross section of Deeply Virtual Compton Scattering (DVCS) in the small-$x_B$ region. We demonstrate that the DVCS cross section becomes independent of energy in the limit of very small $x_B$, which clearly indicates saturation of the DVCS cross section. Our predictions for the GPDs and the DVCS cross section at high-energies can be tested at the future Electron-Ion Collider and in ultra-peripheral nucleus-nucleus collisions at the LHC.
