The CLEO Collaboration searched 9.6 million $ B\bar{B} $ events for lepton-flavor-violating decays of B mesons, including $ B \rightarrow he^{\pm}\mu^{\mp} $, $ B^{+} \rightarrow h^{-}e^{+}e^{+} $, $ B^{+} \rightarrow h^{-}e^{+}\mu^{+} $, and $ B^{+} \rightarrow h^{-}\mu^{+}\mu^{+} $, where h is $ \pi $, K, $ \rho $, and $ K^{*}(892) $. No evidence for these decays was found, and 90% confidence level upper limits on their branching fractions were determined, ranging from 1.0 to $ 8.3 \times 10^{-6} $. The Standard Model predicts that certain lepton-flavor-violating decays, such as $ b \to se^{\pm} \mu^{\mp} $ and $ b \to de^{\pm} \mu^{\mp} $, vanish, while others, like $ B \rightarrow K\ell^{+}\ell^{-} $, are predicted to have small but non-zero branching fractions. The CLEO Collaboration used techniques similar to previous studies to search for these decays, including $ K e^{\pm} \mu^{\mp} $, $ B \to K^{*} e^{\pm} \mu^{\mp} $, $ B \to \pi e^{\pm} \mu^{\mp} $, and $ B \to \rho e^{\pm} \mu^{\mp} $, as well as $ B^{+} \rightarrow h^{-} e^{+} e^{+} $, $ h^{-} e^{+} \mu^{+} $, and $ h^{-} \mu^{+} \mu^{+} $. The data were taken with the CLEO detector at the Cornell Electron Storage Ring (CESR), resulting in 9.2 fb$^{-1} $ at the $ \Upsilon(4S) $ resonance and 4.5 fb$^{-1} $ below it. The analysis involved identifying particles such as K and $ \pi $, and distinguishing between signal and background events using an unbinned maximum likelihood method. The results showed no compelling evidence for any of the decays, with statistical significances below 1.2 standard deviations for most, except $ B \to K^{*}e^{\pm}\mu^{\mp} $, which had a significance of 2.0 standard deviations. The CLEO Collaboration placed 90% confidence level upper limits on the branching fractions for the 16 decays, ranging from 1.0The CLEO Collaboration searched 9.6 million $ B\bar{B} $ events for lepton-flavor-violating decays of B mesons, including $ B \rightarrow he^{\pm}\mu^{\mp} $, $ B^{+} \rightarrow h^{-}e^{+}e^{+} $, $ B^{+} \rightarrow h^{-}e^{+}\mu^{+} $, and $ B^{+} \rightarrow h^{-}\mu^{+}\mu^{+} $, where h is $ \pi $, K, $ \rho $, and $ K^{*}(892) $.
