Overview of results on heavy flavor and quarkonia from the CMS collaboration

The non-prompt $J/\psi$ from B-meson decays, the prompt $J/\psi$, the inclusive $\psi'$ and the three $\Upsilon$ states were measured separately using the Compact Muon Solenoid (CMS) experimental apparatus in both \pp and heavy-ion collisions at $\sqrt{s_{_{NN}}} = 2.76$ TeV. The results are based on data collected in 2011 which correspond to an integrated luminosity of 150 $\mu b^{-1}$ of PbPb and 231 $\text{nb}^\text{-1}$ of pp collisions. The yields measured in heavy-collisions are compared to those in pp scaled via the nuclear modification factor, $R_{AA}$. The high-$p_T$ prompt $J/\psi$ shows a suppression that does not vary with rapidity or $p_{T}$. The \raa versus centrality calculated separately for $\Upsilon(1S)$ and $\Upsilon(2S)$, shows less supression for the ground state. An upper limit for $\Upsilon(3S)$ was also calcuated. Combining all the onia states $R_{AA}$ measured by CMS, and considering the binding energy of each state, an ordering of the suppression is observed, which establishes, experimentally, the validity of the sequential melting scenario in heavy-ion collisions. Non-prompt $J/\psi$ $R_{AA}$ dependence with $p_T$ and rapidity was measured in fine bins of centrality. These represent the first detailed measurements, in heavy-ion collision, of the b-quark energy loss kinematic dependence.
