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/psi 3 pi(+)2 pi(-) decay to that of the B-c(+) -> J/psi pi(+) decay is measured to be B(B-c(+) -> J/psi 3 pi(+)2 pi(-))/B(B-c(+) -> J/psi pi(+)) = 1.74 +/- 0.44 +/- 0.24, where the first uncertainty is statistical and the second is systematic. %K Hadron-Hadron Scattering %K QCD %K Branching fraction %K B physics %K Flavor physics %R 10.1007/JHEP05(2014)148 %U http://arxiv.org/abs/arXiv:1404.0287 %U https://doi.org/10.1007/JHEP05(2014)148 %P 148-17pp
