Using up to 474 million BB pairs, we obtain = (69+17 16) modulo 180 . The total uncertainty is dominated by the statistical component, with the experimental and amplitude-model systematic uncertainties amounting to 4 . The corresponding two-standard-deviation region is 41 < < 102 . This result is inconsistent with = 0 with a significance of 5 9 standard deviations. |
