Observation of B 0 → ω K 0 , B + → η π + , and B + → η K + and Study of Related Decays

We present measurements of branching fractions and charge asymmetries for seven B-meson decays with an eta, eta' or omega meson in the final state. The data sample corresponds to 89 million BBbar pairs produced from e+e- annihilation at the Upsilon(4S) resonance. We measure the following branch...

Zusammenfassung:We present measurements of branching fractions and charge asymmetries for seven B-meson decays with an eta, eta' or omega meson in the final state. The data sample corresponds to 89 million BBbar pairs produced from e+e- annihilation at the Upsilon(4S) resonance. We measure the following branching fractions in units of 10^{-6}: B(etapi+)=5.3+/-1.0+/-0.3, B(etaK+)=3.4+/-0.8+/-0.2, B(etaK0)=2.9+/-1.0+/- 0.2 (
