Measurement of the branching fractions for τ−→π−KSπ0ντ and τ−→K−KSπ0ντ

We present a measurement of the branching fractions for τ−→π−KSπ0ντ and τ−→K−KSπ0ντ decays using a data sample containing 616×106τ+τ− pairs accumulated with the Belle detector at the KEKB asymmetric-energy e+e− collider. The branching fractions for τ−→π−KSπ0ντ and τ−→K−KSπ0ντ are found to be (0.192 ± 0.002 ± 0.008)% and (0.074 ± 0.001 ± 0.004)%, respectively.
