We have searched a sample of 9.6 million BB̅ events for the lepton-flavor-violating decays B⃗he±μ∓, B+→h-e+e+, B+→h-e+μ+, and B+→h-μ+μ+, where h is π, K, ρ, and K*(892), a total of sixteen modes. We find no evidence for these decays, and place 90% confidence level upper limits on their branching fractions that range from 1.0 to 8.3×10-6.
