First observation of $B_c^+\to J/\psi \pi^+\pi^-\pi^+$
We observe the $B_c^+\to J/\psi \pi^+\pi^-\pi^+$ decay mode for the first time. The statistical significance is 6.8 standard deviations. This is only the third $B_c^+$ decay mode detected. We measure $BR(B_c^+\to J/\psi \pi^+\pi^-\pi^+)/BR(B_c^+\to J/\psi \pi^+)=3.0\pm0.6\pm0.4$ and find it...
