Evidence for the decay B-c(+) -> J/psi 3 pi(+)2 pi(-)

# metadata.dc.description.abstract[].value
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 the B + c → J/ψ3π +2π − decay to that of the B+ c → J/ψπ+ decay is measured to be B (B+ c → J/ψ3π +2π −) B B + c → J/ψπ+  = 1.74 ± 0.44 ± 0.24, where the first uncertainty is statistical and the second is systemati
