【 摘 要 】

The Compact Muon Solenoid (CMS) has measured various quarkonium states via their decays into muon pairs in pp, PbPb and pPb collisions at √sNN= 2.76 and 5.02 TeV. Quarkonia are especially relevant for studying the quark-gluon plasma since they are produced at early times of the collision and propagate through the medium, mapping its evolution. The most recent results on the production of prompt J=ψ in PbPb and the three υ states in pp and pPb collisions will be presented.
