Measurements of A LR and A lepton from SLD

This paper presents measurements of the leptonic asymmetries in Z decays measured with the SLD detector. Using a data sample of approximately 500,000 Z bosons, we report preliminary values for Ae, A , and A using both hadronic and leptonic decays. When combining all results, we report a preliminary value for the e ective weak mixing angle sin eff W = 0:23110 0:00029.
