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.

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.
