Quarkonia pair production as a tool for study of gluon GPDs

Abstract

In these proceedings we present our results on the exclusive photoproduction of $J/\ddot{I}ˆ\hat{I}{\cdot }_c$ pairs in the collinear factorization framework. We argue that the process might be used as a complementary channel for studying the generalized parton distributions (GPDs) of gluons. We provide numerical estimates for the cross-section in the kinematics of the future Electron Ion Collider.
