Abstract
The observation of the 0b→J/ψ φdecay 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( 0b→J/ψ φ)/B( 0b→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 φand ψ(2S)decays to the reconstructed final states.
