Abstract: We report branching fraction measurements of the decays B+ and B+ based on 711 fb-1 of data collected near the (4S) resonance with the Belle experiment at the KEKB asymmetric-energy e+e- collider. This data sample contains 772 million BB events. One of the two B mesons is fully reconstructed in a hadronic decay mode. Among the remaining ("signal-B") daughters, we search for the ? meson in two decay channels, ???? and ???+?-?0, and reconstruct the ?? meson in ?????+?- with subsequent decay of the ? into ??. Combining the two ? modes and using an extended maximum likelihood, the B+ branching fraction is measured to be (4.2�1.1(stat.)�0.3(syst.))�10-5. For B+, we observe no significant signal and set an upper limit of 0.72�10-4 at 90% confidence level. � 2017 American Physical Society.
