title = "Search for B+ → e+νe and B+ → μ+νμ decays using hadronic tagging",
abstract = "We present a search for the rare leptonic decays B+ → e+νe and B+ → μ+νμ, using the full Υ(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 Υ(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+νe) < 3.5 × 10-6 and B(B+ → μ+νμ) < 2.7 × 10-6 at 90% confidence level.",
