Extensions of the standard model that include new W bosons or extended technicolor gauge bosons can predict sizable changes in the rate of single top-quark production, even when constrained to be consistent with precision electroweak data. We analyze the fractional change in the rate of single top-quark production for several classes of models and determine which ones predict an effect visible at the Fermilab Tevatron collider's run 3.
