Description
The world's largest statistic of tau is collected with Belle detector. Recently, we measure the branching fraction for tau- -> pi- l+ l- nu, which is predicted by the Standard Model but not yet probed due to its small branching fraction (O(10^-5)). In this presentation, we show the measured result of this mode and briefly report the status of other on-going analyses at Belle, the branching fraction of tau decay into three leptons and two neutrinos, the evaluation of Michel parameters using tau- -> l- nu nu and the branching fraction of tau decay into three hadrons and one neutrino.
