Abstract

Evidence is presented for the decay B+c → J/ψ 3π+2π− 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/ψ3π+2π− decay to that of the B+c → J/ψ π+ decay is measured to be

B(B+c → J/ψ 3π+2π−)/B(B+c → J/ψ π+� = 1.74 ± 0.44 ± 0.24

where the first uncertainty is statistical and the second is systematic.
