Search for the rare leptonic decays B+-->l+ nu l (l=e,mu)

We have performed a search for the rare leptonic decays B+-->ℓ+nu ℓ(l=e,mu), using data collected at the Υ(4S) resonance by the BABAR detector at the PEP-II storage ring. In a sample of 468×106 BB[over-bar] pairs we find no evidence for a signal and set an upper limit on the branching fractions B...
