## Abstract

We report on a study of charged and neutral K^{*} production in tau decay. We obtain a branching ratio value BR(τ^{-}→K^{*-}ν_{τ}X^{0}) = (1.43±0.11±0.13)% where X^{0} designates possible unobserved neutral particles (charge conjugate modes are implicit). We observe the first signals for inclusive K^{*0} and K̄^{*0} production in τ^{-} decay, and determine the inclusive branching ratios τ^{-}→K^{*0}K^{-}ν_{τ}X^{0} and τ^{-} K ̄^{*0}π^{-}ν_{τ}X^{0} to be (0.32±0.08±0.12)% and (0.38±0.11±0.13)%, respectively. We have searched for the decay τ^{-}→K^{0}K^{-}ν_{τ}X^{0} and set a limit of 8 × 10^{-3} at 90% confidence level.
