Observation of the decay B+c → J/ψ K + K − π +

The decay B+c → J/ψK + K − π + is observed for the first time, using protonproton collisions collected with the LHCb detector corresponding to an integrated luminosity of 3 fb−1. A signal yield of 78 ± 14 decays is reported with a significance of 6.2 standard deviations. The ratio of the branching f...
