New Gauge Interactions and Single Top Quark Production

Abstract

Extensions of the standard model that include new W bosons or extended technicolor gauge bosons can predict sizeable 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 in the Tevatron collider's Run 3.
