No evidence for a signal was found in any of the decay modes, and we set the following upper limits for the branching fractions: B(τ-→e-KS 0)<2.6 ×10-8, B(τ-→μ-KS 0)<2 .3×10-8, B(τ-→e-KS 0KS 0)<7.1×10-8 and B(τ-→μ-KS 0 KS 0)<8.0×10-8 at the 90% confidence level. © 2010 Elsevier B.V.TauLepton flavor violationB-factoryBelleJetstext::journal::journal article::research article
