Abstract
We report the determination of the Cabibbo-Kobayashi-Maskawa -violating angle through the combination of various measurements involving , , and decays performed by the BABAR experiment at the PEP-II collider at SLAC National Accelerator Laboratory. Using up to 474 million pairs, we obtain modulo 180°. The total uncertainty is dominated by the statistical component, with the experimental and amplitude-model systematic uncertainties amounting to . The corresponding two-standard-deviation region is . This result is inconsistent with with a significance of 5.9 standard deviations.
