Study of the B- -> J/psi K-pi(+)pi(-) decay and measurement of the B- -> X(3872)K- branching fraction
We study the decay B- → J/ΨK -π+π- using 117×106 BB̄ events collected at the Y(4S) resonance with the BABAR detector at the PEP-II e+e- asymmetric-energy storage ring. We measure the branching fractions ℬ (B- → J/ΨK -π+π-) = (116±7(stat.) ±9(syst.))×10-5 and ℬ (B- → X(3872)K-) × ℬ (X(3872) → J/Ψπ+π...
