Abstract

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 at and near a center-of-mass energy of 10.58 GeV. The branching fractions are measured to be B(τ^-→π^-π⁺π ^-ντ)=(8.42±0.00-0.25+0.26)×10^-2, B(τ^-→K^-π⁺π^-ντ) =(3.30±0.01-0.17+0.16)×10^-3, B(τ ^-→K^-K⁺π^-ντ)=(1. 55±0.01-0.05+0.06)×10^-3, and B(τ ^-→K^-K⁺K^-ντ)=(3. 29±0.17-0.20+0.19)×10^-5, where the first uncertainty is statistical and the second is systematic. These branching fractions do not include contributions from modes in which a π⁺π^- pair originates from a KS0 decay. We also present the unfolded invariant mass distributions for these decays.
