Diffractive Photoproduction of Psi(2S) in Photon-Pomeron Reactions in PbPb Collisions at the CERN LHC

This work investigates the exclusive photoproduction of $\psi(2S)$ meson off nuclei evaluating the coherent and the incoherent contributions. The theoretical framework used in the present analysis is the light-cone dipole formalism and predictions are done for PbPb collisions at the CERN-LHC energy of 2.76 TeV. A comparison is done to the recent ALICE Collaboration data for the $\psi(1S)$ state photoproduction.
