Electroweak Symmetry Breaking via a Top Condensation Seesaw Mechanism
We propose a new mechanism in which all of the electroweak symmetry breaking is driven by a natural top quark condensate, produced by {open_quotes}top-color{close_quotes} interactions at a multi-TeV scale. The scheme allows the observed top quark mass, and acceptable T and S parameters, by invoking a seesaw mechanism involving mixing of the top with an additional isosinglet quark. {copyright} {ital 1998} {ital The American Physical Society}
