Measurements of CP-Violating Asymmetries and Branching Fractions in B Decays to omegaK and omegaPi

The authors 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 million B(bar B) pairs produced by e+e- annihilation at the Υ(4S) resonance. For the decay B0 → ωKS0, they measure the time-dependent CP-violation parameters S = 0.51-0.39+0.35 ± 0.02, and C = -0.55-0.26+0.28 ± 0.03. They also measure the branching fractions, in units of 10-6, Β(B+ → ωπ+) = 6.1 ± 0.7 ± 0.4, Β(B+ → ωK+) = 6.1 ± 0.6 ± 0.4, and Β(B0 → ωK0) = 6.2 ± 1.0 ± 0.4, and charge asymmetries Αch(B+ → ωπ+) = -0.01 ± 0.10 ± 0.01 and Αch(B+ → ωK+) = 0.05 ± 0.09 ± 0.01
