Studies of quarkonium production and polarization play an important role in understanding QCD. CMS has recently measured the ϒ(nS) (n=1,2,3) production cross sections and polarizations, as well as the prompt ψ(nS) (n=1,2) polarizations, using a dimuon sample collected in proton-proton collisions in 2011 at √ s = 7 TeV. The differential cross sections of the ϒ(nS) states are presented * Speaker.
