Study of τ−→h−h+h−ντ decays at Belle

We present a study of τ−→π−π+π−ντ, τ−→K−π+π−ντ, τ−→K−K+π−ντ, and τ−→K−K+K+ντ decays using a data sample collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. The final results on the branching fractions of these four decay modes are given. We also obtain the unfolded mass spectra of the three-body hadronic system for these decays.
