Abstract
Differential production cross sections of prompt and charmonium and () bottomonium states are measured in proton–proton collisions at , with data collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 2.3 fb−1 for the and 2.7 fb−1 for the other mesons. The five quarkonium states are reconstructed in the dimuon decay channel, for dimuon rapidity . 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 to , to , and to production.
