Abstract (summary)

We set a preliminary 95% C.L. exclusion on the oscillation frequency of [special characters omitted] mixing using a sample of 400,000 hadronic Z 0 decays collected by the SLD experiment at the SLC during the 1996–98 run. In this analysis, [special characters omitted] mesons are partially reconstructed by combining a fully reconstructed Ds with other [special characters omitted] decay products. The Ds decays are reconstructed via the &phis;π and K*K channels. The b-hadron flavor at production is determined by exploiting the large forward-backward asymmetry of polarized Z0 bb¯ decays as well as information from the hemisphere opposite to the reconstructed B decay. The flavor of the [special characters omitted] at the decay vertex is determined by the charge of the D s. A total of 361 candidates passed the final event selection cuts. This analysis excludes the following values of the [special characters omitted] mixing oscillation frequency: Δms < 1.4 psec−1 and 2.5 < Δms < 5.3 psec−1 at the 95% confidence level.
