Abstract Differential production cross sections of J/ψ and ψ(2S) charmonium and Υ(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 fb1 for the J/ψ and 2.7 fb1 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 ψ(2S) to J/ψ, Υ(2S) to Υ(1S), and Υ(3S) to Υ(1S) production.
