Measurement of quarkonium production cross sections in pp collisions at s=13TeV
Differential production cross sections of prompt 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 fb−1 for the J/ψ an...

| Summary: | Differential production cross sections of prompt 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 fb−1
for the J/ψ 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 ψ(2S) to J/ψ, Υ(2S)
to Υ(1S), and Υ(3S) to Υ(1S) production. |
