Observation of B+→J/ψ3π+2π− and B+→ψ(2S)π+π+π− decays.
- Abstract:
- 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 of B+→ψ(2S)K+ are measured to be B(B+ → J/ ψ3π+2π−)/B(B+ → ψ (2S)K+) = (1.88±0.17±0.09)×10^−2, B(B+ → ψ (2S)π+π+π−)/B(B+ → ψ (2S)K+) = (3.04±0.50±0.26)×10^−2,where the first uncertainties are statistical and the second are systematic.
