dc.description.abstract | The observation of the 0 b → J/ψφ decay is reported using proton-proton collision data collected at √s = 13 TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity of 60 fb−1. The ratio of the branching fractions B(0 b → J/ψφ)/B(0 b → ψ(2S)) is measured to be (8.26 ± 0.90 (stat) ± 0.68 (syst) ± 0.11(B)) × 10−2, where the first uncertainty is statistical, the second is systematic, and the last uncertainty reflects the uncertainties in the world-average branching fractions of φ and ψ(2S) decays to the reconstructed final states. | en |
