Observation of B0 → ωK0, B+ → ηπ+, and B+ → ηK+ and Study of Related Decays

Abstract:
The branching fractions and charge asymmetries for seven B-meson decays were measured. A combination of a vertex tracker (SVT) and a 40-layer central drift chamber was used to detect and measure the momenta of the Charged particles from the e+e-. Photon and electrons were identified using a CsI(Tl) electromagnetic calorimeter (EMC). The results show that the values of signal charge asymmetries for the two decays with ω mesons were small, as expected theoretically.
