Description

We present measurements of the branching fractions for B0-meson decays to η'K0 and ωK0, and of the branching fractions and CP-violation charge asymmetries for B+-meson decays to ηπ+, ηK+, η'π+, η'K+, ωπ+, and ωK+. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 383x106 BB pairs produced in e+e- annihilation. The measurements agree with previous results; we find no evidence for direct CP violation
