SLD results from the study of polarized Z 0 produced at the SLC ?

The results obtained during the 1992 run of the SLD detector at the SLC are reviewed together with the general performances of the machine. The first measurement of the left-right asymmetry, the determination of the Z0 branching ratio to bottom quarks and the measurement of αs are presented. Current plans and expectations for the 1993 run, when high polarization (≥ 60%) GaAs strained cathodes sources will be used, are described.
