Exclusive photoproduction of quarkonium in proton-nucleus collisions at energies available at the CERN Large Hadron Collider

摘要

In this work we investigate the coherent photoproduction of psi(1S), psi(2S)and Upsilon (1S) states in the proton-nucleus collisions in the LHC energies.Predictions for the rapidity distributions are presented using the color dipoleformalism and including saturation effects that are expected to be relevant athigh energies. Calculations are done at the energy 5.02 TeV and also for thenext LHC run at 8.8 TeV in proton-lead mode. Discussion is performed on themain theoretical uncertainties associated to the calculations.
