Direct Tests of Dynamical Electroweak Symmetry Breaking

Abstract

We review the connection between $m_t$ and the $Zb\bar{b}$ vertex in ETC models and discuss the resulting experimental constraint on models with weak-singlet ETC bosons. We mention several recent efforts to bring ETC models into agreement with this constraint, and explore the most promising one (non-commuting ETC) in detail.
