Abstract
The implications of the recent measurement of the left-right asymmetry, , by the SLD Collaboration for theories with extended gauge sectors is examined. We show that it is possible to arrange for large, negative values of , based on an analysis of leptonic data, without serious side effects for other observables in certain classes of models. The implications of such scenarios for future measurements on the peak, at the Tevatron, and for atomic parity violation experiments are examined.
