Summary
The cross section for Bhabah scattering (e⁺e{sup −} → e⁺e{sup −}) with polarized electrons at the center of mass energy of the Z° resonance has been measured with the SLD experiment at the SLAC Linear Collider (SLC) during the 1992--1993 runs. The first measurement of the left-right asymmetry in Bhabah scattering (A{sub LR}{sup e+}e{sup −} (θ)) is presented. From A{sub LR}{sup e+}{sup −} (Θ) the effective weak mixing angle is measured to be sin²θ{sub W}{sup eff} = 0.2245±0.0010. When combined with the measurement of A{sub LR}, the effective electron couplings are measured to be v{sub e} = −0.0414±0.0020 and a{sub e} = −0.4977±0.0045.
