Abstract: The polarization asymmetry of the Z° is a highly accurate measure of the Z° coupling to fermions and significant as a precision test of the Standard Model. We summarize the role of electroweak symmetry‐breaking and radiative corrections; the non‐decoupling of new physics beyond the Z°; and the testing of extensions of the Standard Model, such as supersymmetry, technicolor, new generations of fermions, grand unification, and new gauge forces. Also discussed are the relationship of the polarization asymmetry to other electroweak observables and its superiority to other Z° asymmetries.
