Quarkonium production in pp collisions at 7 TeV

We present a selection of quarkonium production results obtained by the CMS experiment, on the basis of data collected in proton-proton collisions at a centre-of-mass energy of 7 TeV. The measurements include the production cross sections of prompt and non-prompt J/$\psi$ mesons, as well as the frac...

Sumario:We present a selection of quarkonium production results obtained by the CMS experiment, on the basis of data collected in proton-proton collisions at a centre-of-mass energy of 7 TeV. The measurements include the production cross sections of prompt and non-prompt J/$\psi$ mesons, as well as the fraction of J/$\psi$ production due to b hadron decays, as a function of transverse momentum and in several rapidity ranges. The production cross sections of the $\Upsilon$ states are also presented, as well as their ratios, up to values of transverse momentum not previously explored.
