Abstract
The photoproduction of vector mesons in ultra-peripheral collisions (UPC) is a powerful tool to probe the nuclear gluon distribution (Pb-Pb collisions) and the gluon structure function in the proton (p-Pb collisions). The first measurements of coherent photoproduced J/ψ and ψ(2S) in Pb-Pb collisions at √sNN = 2.76TeV, performed with the ALICE detector, are reported and compared to STARLIGHT and QCD based models, in order to investigate nuclear gluon shadowing. The first results of the measurement of exclusive J/ψ photoproduction off protons in p-Pb collisions at √sNN = 5.02TeV performed by the ALICE Collaboration are also mentioned.
