Search for lepton-number violating B+→X-ℓ+ℓ'+ decays
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.
