Description

The Compact Muon Solenoid (CMS) is fully equipped to measure hard probes in the di-muon decay channel in the high multiplicity environment of nucleus-nucleus collisions. Such probes are especially relevant for studying the quark-gluon plasma since they are produced at early times and propagate through the medium, mapping its evolution. CMS has measured the nuclear modification factors of non-prompt J/psi (from b-hadron decays), prompt J/psi, and Y(1S) in PbPb collisions at $\sqrt{s_{NN}} = 2.76$ TeV. Suppression of the excited Y-states is also studied in comparison to the Y(1S) state.
