Abstract
Differential production cross sections of prompt J/Ï and Ï(2S) charmonium and Ï(nS) (n=1,2,3) bottomonium states are measured in proton-proton collisions at s=13TeV, with data collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 2.3 fbâ1 for the J/Ï and 2.7 fbâ1 for the other mesons. The five quarkonium states are reconstructed in the dimuon decay channel, for dimuon rapidity |y|<1.2. The double-differential cross sections for each state are measured as a function of y and transverse momentum, and compared to theoretical expectations. In addition, ratios are presented of cross sections for prompt Ï(2S) to J/Ï, Ï(2S) to Ï(1S), and Ï(3S) to Ï(1S) production.
