Description
Charged lepton flavor violation (CLFV) is forbidden in the Standard Model but possible in several new physics scenarios. Thus, the observation of CLFV would be a clear signature of new physics. We report the world-leading result of lepton-flavor-violating decays of \tau lepton decays into a light charged lepton ($\ell$ = e, $\mu$) and a vector meson using the full data sample collected by the Belle. In addition, we report the searches for new physics in $\tau$ decays, especially with its decay involving heavy neutral lepton. We also cover recent searches for tau decays into a scalar non-standard-model particle and a light charged lepton. The results are based on the data set collected by the Belle experiment at the KEKB asymmetric-energy $e^{+}e^{-}$ collider.
