Measurement of quarkonium production cross sections in pp collisions at $\sqrt s$ = 13 TeV


Abstract

Differential production cross sections of prompt $J/\psi$ and $\psi (2S)$charmonium and $\gamma (nS) (n=1,2,3)$ bottomonium states are measured in proton–proton collisions at $\sqrt s=13 TeV$, with data collected by the CMS detector at the LHC, corresponding to an integrated luminosity of $2.3 fb^{−1}$ for the and $2.7fb^{−1}$ for the other mesons. The five quarkonium states are reconstructed in the dimuon decay channel, for dimuon rapidity $\left | y \right |< 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 to $\psi (2S)$ to $J/\psi$, $\gamma (2S)$ to $\gamma(1S)$, and $\gamma (3S)$ to $\gamma (1S)$, production.
