The electroweak polarization asymmetry: A guided tour
A comprehensive review is provided of the electroweak polarization asymmetry at the Z/sup 0/, a highly accurate measure of the Z/sup 0/ coupling to fermions. Its significance as a precision test of the Standard Model is explored in detail. Emphasized are the role of electroweak symmetry-breaking and radiative corrections; the non-decoupling of new physics beyond the Z/sup 0/; 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/sup 0/ asymmetries. Experimental issues are briefly presented, stressing the importance of polarization at the SLC and LEP e/sup +/e/sup -/ colliders. 42 refs., 13 figs., 2 tabs.
