【 摘 要 】

We summarize the results from the study of charmonium and bottomonium via the dimuon decay channel in PbPb collisions with the CMS experiment. We discuss the observation of sequential suppression of the Υ states. We present preliminary results of prompt J/ψ and ψ' production, as well as of non-prompt J/ψ's coming from the weak decay of b-quarks. This latter measurement is sensitive to b-quark energy loss. We discuss the results and compare to model predictions.
