Description
Recent measurements from ALICE, CMS and LHCb Collaboration of exclusive production of J/ψ mesons in ultraperipheral heavy-ion collisions at the LHC have given us new access to the interaction of small color dipoles with cold nuclear matter. We discuss the role of cc̄ g-Fock states in the diffractive photoproduction of J/ψ-mesons. We have demonstrated, that the inclusion of inelastic shadowing due to high-mass diffractive states leads to an additional suppression of the coherent J/ψ photoproduction on lead. We observe that incorporation of cc̄ g-states improves agreement of the dipole approach with the midrapidity data of the ALICE collaboration.
