Abstract
Differential production cross sections of prompt J/ and (2S) charmonium and (nS) (n = 1, 2, 3) bottomonium states are measured in proton-proton collisions at s = 13 TeV, with data collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 2.3 fb -1 for the J/ and 2.7 fb -1 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 (2S) to J/, (2S) to (1S), and (3S) to (1S) production.
