We present a search for the lepton-flavor-violating decays, where, using the full data sample ofpairs recorded by the Belle detector at the KEKB asymmetric-energycollider. We use events in which onemeson is fully reconstructed in a hadronic decay mode. Thelepton is reconstructed indirectly using the momentum of the reconstructedand that of thefrom the signal decay. We find no evidence fordecays and set upper limits on their branching fractions at 90% confidence level ofand.
