Abstract
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

where the first uncertainty is statistical and the second is systematic
