We present a measurement of the branching fractions and charge-parity-(CP-)violating parameters in B??K decays. The results are obtained from the final data sample containing 772�106 BB? pairs collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the branching fractions B(B0??K0)=(4.5�0.4(stat)�0.3(syst))�10-6, B(B+??K+)=(6.8�0.4(stat)�0.4(syst))�10-6 which are in agreement with their respective current world averages. For the CP-violating parameters, we obtain A?KS0=-0.36�0.19(stat)�0. 05(syst),S?KS0=+0.91�0.32(stat)�0.05(syst),A?K+=-0. 03�0.04(stat)�0.01(syst), where A and S represent the direct and mixing-induced CP asymmetry, respectively. We find no evidence of CP violation in the decay channel B+??K+; however, we obtain the first evidence of CP violation in the B0??KS0 decay channel at the level of 3.1 standard deviations. � 2014 American Physical Society. |
