Quarkonia and heavy-flavour production in CMS

The Compact Muon Solenoid (CMS) has measured numerous quarkonium states via their decays into μ+μ− pairs in pp and PbPb collisions at sNN=2.76TeV. Quarkonia are especially relevant for studying the quark-gluon plasma since they are produced at early times and propagate through the medium, mapping its evolution. Non-prompt J/ψ from b-hadron decays show a strong suppression in the transverse momentum range (6.5
