We report a study of τ lepton decays involving K S 0 with a 669 fb −1 data sample accumulated with the Belle detector at the KEKB asymmetric-energy e + e − collider. The branching fractions have been measured for the τ − → π − K S 0 ν τ , K − K S 0 ν τ , π − K S 0 π 0 ν τ , K − K S 0 π 0 ν τ , π − K S 0 K S 0 ν τ and π − K S 0 K S 0 π 0 ν τ decays. We also provide the unfolded mass spectra for τ − → π − K S 0 π 0 ν τ and τ − → K − K S 0 π 0 ν τ . [ABSTRACT FROM AUTHOR]
