Abstract
A search for B[subscript s][superscript 0]-B[subscript s][superscript 0̅] oscillations is performed using a sample of 400 000 hadronic Z[superscript 0] decays collected by the SLAC Large Detector experiment. The B[subscript s][superscript 0] candidates are reconstructed in the B[subscript s][superscript 0]→D[subscript s][superscript -]X channel with D[subscript s][superscript -]→φπ[superscript -], K[superscript *0]K[superscript -]. The B[subscript s][superscript 0] production flavor is determined using the large forward-backward asymmetry of polarized Z[superscript 0]→bb̅ decays and charge information in the hemisphere opposite that of the B[subscript s][superscript 0] candidate. The decay flavor is tagged by the charge of the D[subscript s][superscript ±]. From a sample of 361 candidates with an average B[subscript s][superscript 0] purity of 40%, we exclude the following values of the oscillation frequency: Δm[subscript s]<1.4ps[superscript -1] and 2.4<Δm[subscript s]<5.3ps[superscript -1] at the 95% confidence level.
