Description
It is investigated the exclusive production of quarkonium states in proton-proton and nucleus-nucleus collisions at the LHC employing the light-cone dipole formalism theoretical framework. We calculate the rapidity, amd specially the tranverse momentum distributions for J/Psi´s and Upsilons, and excited states. Our results are compared to recent experimental data (ALICE and LHCb), and predictions are done for the next LHC data taken in ultraperipheral collisions. The results are discussed in order to critisize the robustness of the formulation to express the effects of QCD at low-x for those systems.
