Abstract
We present direct measurements of the Z(0)-lepton coupling asymmetry p arameters A(e), A(mu), and A(tau), based on a data sample of 12063 lep tonic Z(0) decays collected by the SLD detector. The Z bosons are prod uced in collisions of beams of polarized e(-) with unpolarized e(+) at the SLAG Linear Collider. The couplings are extracted from the measur ement of the left-right and forward-backward asymmetries for each lept on species, The results are A(e) = 0.152 +/- 0.012(stat) +/- 0,.001(sy st), A(mu) 0.102 +/- 0.034 +/- 0.002, and A(tau) = 0.195 +/- 0.034 +/- 0.003.
