ALICE results on ultra-peripheral p-Pb and Pb-Pb collisions
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 ultraperipheral Pb-Pb and p-Pb collisions (UPC). Exclusive photoproduction of vector mesons is sensitive to the gluon distribution of the interacting target (proton or nucleus). The reactions allow one to study saturation phenomena and nuclear gluon shadowing. Here we present results from the ALICE measurement of coherent photoproduction in Pb-Pb UPC at root s<inf>NN</inf> = 2.76 TeV of J/Φ mesons at forward and central rapidity and ρ<sup>0</sup> and Φ(2S) mesons at central rapidity. Furthermore, we also show our results on the J/Φ photoproduction in p-Pb UPC at root s<inf>NN</inf> = 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.
