Book excerpt: The completion of the SLD experiment marks the end of a very productive decade of the Z-pole physics, which brought dramatic improvements in the accuracy of electroweak measurements. Experimental study of the ee− 2!Z° 2!f{bar f} process, started about 11 years ago by the Mark II collaboration, proved to be an excellent source of electroweak information. The SLD and the four LEP experiments are now wrapping up their Z-pole data analyses. This thesis presents the final results of the left-right Z° boson production cross section asymmetry (A{sub LR}°) measurement (which is unambiguously related to the effective electroweak mixing angle, sin 2 [theta]{sub W}{sup eff}), based on the full data sample collected by the SLD collaboration. I will focus on the two latest SLD runs: 1996 and 1997/98. The analysis procedures used in previous runs are described in the theses by Ross King [1], Amitabh Lath [2], Robert Elia [3], and in the three Physical Review Letters [4, 5, 6].
