我们搜索了960万个BB-bar事件的样本，寻找违反轻子味道的衰变B—> he ^{+-} mu^{-+}, B^+—> h^- e^+ e^+, B^+—> h^- e^+ mu^+和B^+—> h^- mu^+ mu^+，其中h为pi， K， rho和K*(892)，共16种模式。我们没有发现这些衰变的证据，并对它们的分支分数设置了90%置信水平的上限，范围从1.0到8.3 X 10^{-6}。
We have searched a sample of 9.6 million BB-bar events for the lepton-flavor-violating decays B --> h e^{+-} mu^{-+}, B^+ --> h^- e^+ e^+, B^+ --> h^- e^+ mu^+, and B^+ --> h^- mu^+ mu^+, where h is pi, K, rho, 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 X 10^{-6}.
