Abstract

Exclusive J/ψ production is investigated in proton-proton collisions employing GPD approach with GK model. Three sets gluon density are used to calculate exclusive J/ψ production. The survival factors and equivalent photon approximation are applied to predict the exclusive J/ψ photoproduction in proton-proton collisions. The GPD method prediction gives a good agreement with the experimental data at LHCb. The exclusive J/ψ production is given in proton-proton collisions at RHIC and NICA. These predictions of GPD approach can be employed to estimate the exclusive J/ψ cross sections in future proton-proton collisions.
