Evidence for the decay B+c→J/ψ3π+2π−

Evidence is presented for the decay B+c→J/ψ3π+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...
