Abstract

We report on a search for eleven lepton-number violating processes B+X++ with X=K, π, ρ, K*, or D and +/+=e+ or μ+, using a sample of 471±3 million BB¯ events collected with the BABAR detector at the PEP-II e+e collider at the SLAC National Accelerator Laboratory. We find no evidence for any of these modes and place 90% confidence level upper limits on their branching fractions in the range (1.526)×107.
