Abstract
We report on a search for eleven lepton-number violating processes B^+→X^−ℓ^+ℓ'^+ with X^−=K^−, π^−, ρ^−, K^(*−), or D^− and ℓ^+/ℓ'^+=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 (1.5–26)×10_(−7).
