Measurements of AP{sub LR}, A{sub lepton} and A{sub b} from SLD
- SLAC
We present the measurements of the leptonic asymmetries in Z{sup 0} decays measured by the SLD experiment at SLAC. A data sample of approximately 550,000 Z{sup 0} bosons are used for the preliminary measurement of A{sub LR}(A{sub e}) and the leptonic final state measurements of A{sub e}, A{sub {mu}} and A{sub {tau}}, representing the entire set of 1992-1998 SLD runs. When combining all results, a preliminary value for the effective weak mixing angle is obtained: sin{sup 2} {theta}{sub W}{sup eff} = 0.23109 {+-} 0.00029. We also present the direct measurements of A{sub b} from left-right forward-backward asymmetries, using partial data samples from 1993-1998 SLD runs. The preliminary value combines jet charge, cascade kaon and semileptonic decay analyses to obtain A{sub b} = 0.866 {+-} 0.036.
