Abstract: We report the first observation of B0?X(3872)(K+?-) and evidence for B+?X(3872)(K0?+). We measure the product of branching fractions for the former to be B(B0?X(3872)(K+?-))�B(X(3872)?J/??+?-)=(7.9�1.3(stat)�0.4(syst))�10-6 and find that B0?X(3872)K?(892)0 does not dominate the B0?X(3872)K+?- decay mode. We also measure B(B+?X(3872)(K0?+))�B(X(3872)?J/??+?-)=(10.6�3.0(stat)�0.9(syst))�10-6. This study is based on the full data sample of 711fb-1 (772�106BB� pairs) collected at the ?(4S) resonance with the Belle detector at the KEKB collider. � 2015 American Physical Society.
