Observation of the decay $B_c^+ \rightarrow J/\psi K^+ K^- \pi^+$

The decay $B_c^+ \rightarrow J/\psi K^+ K^- \pi^+$ is observed for the first time, using proton-proton collisions collected with the LHCb detector corresponding to an integrated luminosity of 3 fb$^{-1}$. A signal yield of 78$\pm$14 decays is reported with a significance of 6.2 standard deviations....

Sumario:The decay $B_c^+ \rightarrow J/\psi K^+ K^- \pi^+$ is observed for the first time, using proton-proton collisions collected with the LHCb detector corresponding to an integrated luminosity of 3 fb$^{-1}$. A signal yield of 78$\pm$14 decays is reported with a significance of 6.2 standard deviations. The ratio of the branching fraction of $B_c^+ \rightarrow J/\psi K^+ K^- \pi^+$ decays to that of $B_c^+ \rightarrow J/\psi \pi^+$ decays is measured to be $0.53\pm 0.10\pm0.05$, where the first uncertainty is statistical and the second is systematic.
