Exclusive photoproduction of J/psi and psi(2S) states in proton-proton
collisions at the CERN LHC

M. B. Gay Ducati, M. T. Griep, M. V. T. Machado
In this work we investigate the exclusive photoproduction of J/psi and the radially excited psi(2S) state off nucleon 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 comparison is done to the recent LHCb Collaboration data for the exclusive charmonium production.
