Description
We report a partial wave analysis conducted in $\tau^{-} \to \pi^{-}\pi^{-}\pi^{+}\nu$ decays, where it is expected that the new resonance $\text{a}_1(1420)$ that has been observed by COMPASS experiment can be studied as well as which provides the detailed study of $\text{a}_1(1260)$. 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 lepton-flavor-violating decays of the tau lepton and a measurement of its electric dipole moment. The results are based on the full data collected with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider.
