Book Description
Z[degrees] bosons have been produced by collisions of longitudinally polarized electrons with unpolarized positrons at the SLAC Linear Collider and their decays have been recorded by the SLD experiment. We present preliminary measurements of the properties of the resulting Z[degrees] decays into multi-hadronic final states. We find good agreement with the predictions of perturbative QCD and fragmentation models.

Book Description
In 1992 the SLD experiment at SLAC collected over 11,000 hadronic decay events of Z[sup 0] bosons produced in collisions of polarised electrons with unpolarised positrons delivered by the SLC. Preliminary experimental results are presented on tests of the value of the gluon spin involving events containing three hadronic jets measured in the final state. A leading order QCD prediction is found to be in agreement with the data, whilst a model including scalar gluons is clearly excluded. Effects of the electron beam polarisation upon the orientation of the three-jet event plane are discussed.

Book Description
We present preliminary evidence for leading particle production in hadronic decays of the Z[sup 0] to light quark pairs using 150,000 events recorded in the SLD experiment at SLAC. The highly polarized electron beam produced by the SLC is used to tag quark and antiquark jets, and a signed impact parameter technique is employed to reject heavy flavor events. Charged hadrons are identified in the SLD Cherenkov Ring Imaging Detector (CRID) and[Lambda]/[bar[Lambda]] are reconstructed using their charged decay modes. In a high purity sample of quark jets, the baryon momentum spectrum is harder that that of the antibaryon, and conversely for a sample of antiquark jets, supporting the hypothesis that the faster particles in jets are more likely to carry the primary quark or antiquark from the Z[sup 0] decay. Similarly, more high momentum K[sup -] that K[sup+] are observed in quark jets and conversely for antiquark jets, consistent with the hypothesis that leading K[sup[+-]] are produced predominantly in s[bar s] events rather than[ital u][bar[ital u]] events.
