Abstract

Evidence is presented for the decay B+ c→J/ω3φ+2φ - using proton-proton collision data, corresponding to an integrated luminosity of 3 fb?1, collected with the LHCb detector. A signal yield of 32 ± 8 decays is found with a significance of 4.5 standard deviations. The ratio of the branching fraction of the B+ c→J/ω3φ+2φ - decay to that of the B+ c→J/ω3φ+2φ -decay is measured to be B (B+ c→J/ω3φ+2φ -) B+ c→J/ω3φ+2φ - = 1.74 ± 0.44 ± 0.24, where the first uncertainty is statistical and the second is systematic.
