$J/\psi$ photoproduction in Pb-Pb and p-Pb ultra-peripheral collisions with ALICE at LHC
The photoproduction of vector mesons in Ultra-Peripheral Collisions (UPC) is a powerful tool to probe the nuclear gluon distribution, for which there is considerable uncertainty in the low-x region. We present the first measurements in Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV, performed with the...
