Evidence for the decay $B_c^{+}\to J/\psi 3{\pi }^{+}2{\pi }^{-}$

LHCb collaboration, R. Aaij, B. Adeva +686

Evidence is presented for the decay $B_c+\to J/\psi 3{\pi }^{+}2{\pi }^{-}$ using proton-proton collision data, corresponding to an integrated luminosity of 3fb${}^{-1}$, collected with the LH…
