Observation of B+→J/ψ3π+2π− and B+→ψ(2S)π+π+π− decays.
The decays B+→J/ψ3π+2π− and B+→ψ(2S)π+π+π− are observed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb^-1, collected by the LHCb experiment in proton-proton collisions at the centre-of-mass energies of 7 and 8TeV. The branching fractions relative to that o...
