Abstract

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