Heavy-Flavor Results at CMS

Using large data samples of di-muon events, CMS has performed detailed measurements in the field of quarkonium production. Differential cross-sections of J/psi, psi(2S) and Y(nS) states in pT and rapidity will be presented, separated in prompt and non-prompt contributions for the charmonium case: experimental results are compared with recent predictions in the context of NLO nonrelativistic QCD and the FONLL scheme. Studies of P-wave charmonia and bottomonia ($\chi_{c}$, $\chi_{b}$), using the decay mode (J/psi, Y) + gamma where the photon converts in an e+e- pair inside the detector, will be discussed. Recent results on B-baryons and B rare decays will be also presented.
