Description

In this talk we analyze exclusive photoproduction of heavy quarkonia pairs in the kinematics of moderate values of Bjorken variable 𝑥𝐵. We discuss the relation of various observables to gluonic generalized parton distributions (GPDs) of the target. We demonstrate that the largest cross-section has exclusive production of 𝐽/𝜓𝜂𝑐 pairs, which gets the dominant contribution from the unpolarized gluon GPDs 𝐻𝑔, 𝐸𝑔. We provide numerical estimates for the cross-section in the kinematics of the future Electron Ion Collider.
