ALICE recent results on photoproduction in ultra- peripheral collisions at the LHC

Presented by Mr. Andrea AGOSTINELLI on 31 May 2013 from 3:00 PM to 3:25 PM


Ultra-relativistic heavy ions generate strong electromagnetic fields which offer the possibility to study γ-γ and γ-nucleus processes at the LHC in the so called ultra-peripheral collisions (UPC). The photoproduction of J/ψ vector mesons in UPC is sensitive to the gluon distribution of the interacting nuclei. Here, we report on ALICE results of coherent and incoherent J/ψ production measured in Pb-Pb collisions at √sNN = 2.76 TeV. The J/ψ has been measured via its leptonic decay both in the rapidity range -3.6 < y < -2.6 and -0.9 < y < 0.9. We also report on the latest results in the study of photo-production processes in p-Pb collisions.
