Abstract
We present a search for the lepton flavor violating decays , with , using the full data sample of pairs recorded by the Belle detector at the KEKB asymmetric-energy collider. We use events in which one meson is fully reconstructed in a hadronic decay mode. We find no evidence for decays and set upper limits on their branching fractions at the 90% confidence level in the range. The obtained limits are the world’s best results.
