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 666fb^-1 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.
