Abstract

We have searched for the lepton flavor violating decays τ^- → ℓ^- K_S⁰ (ℓ = e or μ), using a data sample of 281 fb^-1 collected with the Belle detector at the KEKB e⁺ e^- asymmetric-energy collider. No evidence for a signal was found in either of the decay modes, and we set the following upper limits for the branching fractions: B (τ^- → e^- K_S⁰) < 5.6 × 10^-8 and B (τ^- → μ^- K_S⁰) < 4.9 × 10^-8 at the 90% confidence level. These results improve the previously published limits set by the CLEO Collaboration by factors of 16 and 19, respectively.
