Abstract

The inclusive production of K S O mesons τ lepton decay has been studied using the high resolution spectrometer at the PEP e +e − storage ring operated at √ s=29 GeV. The data sample corresponds to an integrated luminosity of 300pb −1. The measured branching fraction is B( τ −→K S OX − ν τ ) = (0.64±0.15)%. The measurement is consistent with all K S O coming from the Cabibbo-suppressed decay τ −→ K ∗−(890)ν τ with a branching ratio of (1.9±0.3±0.4)%.
