J/psi photoproduction in ultra-peripheral Pb-Pb and p-Pb collisions with the ALICE detector

Original language description

Ultra-relativistic heavy ions generate strong electromagnetic fields which offer the possibility to study gamma gamma, gamma-nucleus and gamma-proton processes at the LHC in ultra-peripheral Pb-Pb and p-Pb collisions (UPC). Exclusive photoproduction of J/psi vector mesons is sensitive to the gluon distribution of the interacting target (proton or nucleus). This process is expected to be sensitive to saturation phenomena and nuclear gluon shadowing. Here we report on the ALICE measurement of J/psi coherent photoproduction in Pb-Pb UPC at root S-NN = 2.76 TeV at forward and central rapidities. Furthermore, we also present results on the J/psi photoproduction in p-Pb UPC at root S-NN = 5.02 TeV in the forward and backward rapidities, where the rapidity is measured in the laboratory frame with respect to the proton beam direction. The J/psi mesons have been identified through their leptonic decays.
