Chiral Technicolor and Precision Electroweak Measurements

Abstract

I consider the possibility that electroweak symmetry is broken by a strongly interacting chiral gauge theory. I argue that some of the discrepancies between precision electroweak measurements and the predictions of QCD-like technicolor models can be resolved if technicolor is a chiral gauge theory. I present a toy technicolor model which demonstrates this idea, and gives $m_t\gg m_b$, with a small value for $\Delta {\rho }_{\ast }\equiv \alpha T$, and small corrections to $Z\to b\overline{b}$.
