Abstract
A search for oscillations is performed using a sample of 400 000 hadronic decays collected by the SLAC Large Detector experiment. The candidates are reconstructed in the channel with The production flavor is determined using the large forward-backward asymmetry of polarized decays and charge information in the hemisphere opposite that of the candidate. The decay flavor is tagged by the charge of the From a sample of 361 candidates with an average purity of 40%, we exclude the following values of the oscillation frequency: and at the 95% confidence level.
