Observation of B meson decays to b(1)pi and b(1)K

Abstract:

We present the results of searches for decays of B mesons to final states with a b1 meson and a charged pion or kaon. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 382×106 BB̄ pairs produced in e+e- annihilation. The results for the branching fractions are, in units of 10-6, B(B+→b10π+)=6.7±1.7±1.0, B(B+→b10K+)=9.1±1.7±1.0, B(B0→b1π±)=10. 9±1.2±0.9, and B(B0→b1-K+)=7.4±1.0±1.0, with the assumption that B(b1→ωπ)=1. We also measure charge and f...
