abstract = {The observation of the  L0b --> J/psLf decay is reported using proton-proton collision data collected at s=13TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity of 60fb-1. The ratio of the branching fractionsV(Lob --> J/psLf) /V(Lob --> ps (2S) L 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 f and ps(2S) decays to the reconstructed final states.},
