J/ψ production in p-Pb collisions with ALICE at the LHC

The ALICE Collaboration has measured the inclusive J/ψ production in p-Pb collisions at the nucleon-nucleon center-of-mass energy sNN=5.02TeV. The comparison of the results on the nuclear modification factor as a function of rapidity and transverse momentum with theoretical predictions shows a fair agreement with a shadowing based model and energy loss models with or without a shadowing contribution. The J/ψ production has also been measured by computing the J/ψ nuclear modification factor as a function of the event activity, as well as the yield and mean transverse momentum dependence with the relative charged-particle multiplicity measured at mid-rapidity.
