Abstract

We present measurements of CP-violating asymmetries and branching fractions for the decays B+→ωπ+, B+→ωK+, and B0→ωK0. The data sample corresponds to 232×106 B¯¯¯B pairs produced by e+e− annihilation at the Υ(4S) resonance. For the decay B0→ωK0S, we measure the time-dependent CP-violation parameters S=0.51+0.35−0.39±0.02, and C=−0.55+0.28−0.26±0.03. We also measure the branching fractions, in units of 10−6, B(B+→ωπ+)=6.1±0.7±0.4, B(B+→ωK+)=6.1±0.6±0.4, and B(B0→ωK0)=6.2±1.0±0.4, and charge asymmetries Ach(B+→ωπ+)=−0.01±0.10±0.01 and Ach(B+→ωK+)=0.05±0.09±0.01.
