Abstract: We present a search for the rare leptonic decays B+ ? e+?e and B+ ? ?+??, using the full ?(4S) data sample of 772 � 106 B B� pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. One of the B mesons from the ?(4S) ? B B� decay is fully reconstructed in a hadronic mode, while the recoiling side is analyzed for the signal decay. We find no evidence of a signal in any of the decay modes. Upper limits of the corresponding branching fractions are determined as B(B+ ? e+?e) < 3.5 � 10-6 and B(B+ ? ?+??) < 2.7 � 10-6 at 90% confidence level. � 2015 American Physical Society.
