Decays of $\tau$ leptons to final states containing $K_S^0$ mesons

Using data collected with the CLEO II detector at the Cornell Electron Storage Ring, we have studied the decays of $\tau$ leptons produced through $e^{+}{e}^{-}$ annihilation into final states containing $K_S^0$ mesons, observed through their decays to ${\pi }^{+}{\pi }^{-}$. We present branching fractions for decays to five final states: ${\tau }^{-}\to K^0{h}^{-}{\nu }_{\tau }$, ${\tau }^{-}\to K^0{h}^{-}{\pi }^0{\nu }_{\tau }$, ${\tau }^{-}\to K^0{K}^{-}{\nu }_{\tau }$, ${\tau }^{-}\to K^0{K}^{-}{\pi }^0{\nu }_{\tau }$, and ${\tau }^{-}\to K_S^0{K}_S^0{h}^{-}{\nu }_{\tau }$, where $K^0{h}^{-}$ denotes the sum of the processes involving ${\overline{K}}^0{\pi }^{-}$ and $K^0{K}^{-}$ particle combinations. Substructure and mass spectra in these final states are also addressed.
