Latest results on quarkonium production from CMS

The understanding of quarkonium production in heavy-ion collisions requires the inclusion of many phenomena such as dissociation in the QGP, partonic energy loss, statistical recombination, on top of cold nuclear matter effects (modifications of nPDFs, initial-state energy loss, nuclear break-up). The Compact Muon Solenoid (CMS) collaboration has measured variousquarkonium states via their decay into muon pairs in pp, pPb and PbPb collisions at 5.02 TeV, and can address some of these phenomena. In this talk, the most recent CMS results on quarkonium production will be presented.
