摘要：

In this work we investigate the exclusive photoproduction of J/psi and the radially excited psi(2S) state off nucleons in proton-proton collisions. The theoretical framework considered in the analysis is the light-cone dipole formalism and predictions are done for proton-proton collisions at the CERN-LHC energy of 7 TeV. The theoretical uncertainties are investigated and a comparison is made to the recent LHCb Collaboration data for the exclusive charmonium production.
