We have searched a sample of 9.6 million $B\overline{B}$ events for the lepton-flavor-violating decays $\stackrel{\ensuremath{\rightarrow}}{B}{\mathrm{he}}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\mu}}^{\ensuremath{\mp}},$ ${B}^{+}\ensuremath{\rightarrow}{h}^{\ensuremath{-}}{e}^{+}{e}^{+},$ ${B}^{+}\ensuremath{\rightarrow}{h}^{\ensuremath{-}}{e}^{+}{\ensuremath{\mu}}^{+},$ and ${B}^{+}\ensuremath{\rightarrow}{h}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{+},$ where h is $\ensuremath{\pi},$ K, $\ensuremath{\rho},$ 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 …
