Resumo
In the framework of the leading order of perturbative QCD, we study exclusive photoproduction of ψ(2S) mesons in ultraperipheral proton-proton and nucleus-nucleus collisions at the LHC. We calculate the charmonium rapidity distributions and show that the analysis of the LHC experimental data allows one to significantly reduce uncertainties in the behavior of the gluon densities of the proton and nuclei at small x.
