                      channel is presented. This measurement uses a sample of
                      proton-proton collision data collected at a center-of-mass
                      energy of 13 TeV by the CMS experiment in 2018,
                      corresponding to an integrated luminosity of 59.7 fb$^{-1}$.
                      The measured ratio, $R$(J/$\psi$) = 0.17$^{+ 0.18}_{- 0.17}$
                      (stat) $^{+ 0.21}_{- 0.22}$ (syst) $^{+ 0.19}_{- 0.18}$
                      (theo) = 0.17 $\pm$ 0.33, agrees with the value of 0.2582
                      $\pm$ 0.0038 predicted by the standard model, which assumes
                      lepton flavor universality.},
