Measurements of CP-Violating Asymmetries in B Decays to omegaKs
The BABAR Collaboration, B. Aubert
Abstract
We present preliminary measurements of CP-violating asymmetries for the decay omega K0S. The data sample corresponds to 347 million BBbar pairs produced by e+e- annihilation at the Upsilon(4S) resonance. For the decay omega K0S, we measure the time-dependent CP-violation parameters S = 0.62+0.25-0.30+/-0.002, and C = -0.43+0.25-0.23+/-0.03, where the first uncertainty is statistical and the second systematic.
