Description
In this talk we present our theoretical studies of heavy quarkonia pair electro- and photoproduction in the collinear factorization framework. We focus on $J/\psi\ \eta_c$ pair production, and discuss the relation of different observables to generalized parton distributions (GPDs) of gluons. The unpolarized cross-section is dominated by contributions of transversely polarized $J/\psi$ mesons, which in the leading twist is controlled by the unpolarized gluon GPDs $H_g, E_g$. We also discuss other observables which might be sensitive to other GPDs of gluons. We provide numerical estimates in the kinematics of the future Electron Ion Collider.
