Abstract
We have searched a sample of 9.6x10(6) B (B) over bar events for the lepton-flavor-violating leptonic B decays, B-0-->mu(+/-)tau(-/+) and B-0-->e(+/-)tau(-/+). The tau lepton was detected through the decay modes tau-->lnu(ν) over bar, where l=e,mu. There is no indication of a signal, and we obtain the 90% confidence level upper limits B(B-0-->mu(+/-)tau(-/+))<3.8x10(-5) and B(B-0-->e(+/-)tau(-/+))<1.3x10(-4).
