Abstract:
Searches for CP violation in decays of B mesons to three Kπ modes, K±π±, K±π0, KS0π±, the mode K±η′, and the vector-pseudoscalar mode ωpi±. These decay modes have well-measured branching ratios and significant signal yields and are self-tagging. Any possible systematic bias on charge asymmetries is negligible compared to the statistical measurement errors. The dependence of the likelihood function on the charge asymmetry for each of the five decay modes is described. All five modes showed no evidence for CP violation.
