Description
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 also discussed.
