J/ ψ Measurements with the ALICE Experiment at the LHC

We review recent results on J/ψ production measured by the ALICE collaboration at the LHC. For pp collisions at = 7 TeV yields and spectra of inclusive and prompt J/ψ, as well as results on their polarization and the charged particle multiplicity dependence of yields are presented. The nuclear modification factor RAA obtained for inclusive J/ψ at mid-(|y| < 0.9) and forward-rapidities (2.5 < y < 4), covering the pT range down to 0, for centrality selected Pb-Pb collisions are discussed. Also, first results on the J/ψ v2 at forward-rapidities are shown.
