Author(s): Simmons, EH; Chivukula, RS; Terning, J | Abstract: We review the connection between mt and the Zbb vertex in ETC models and demonstrate the power of the resulting experimental constraint on models with weak-singlet ETC bosons. Some efforts to bring ETC models into agreement with experimental data on the Zbb vertex are mentioned, and the most promising one (non-commuting ETC) is discussed in detail.

Physics at LEP

In this contribution I have given a brief survey of some of the most interesting new particle searches which can be performed at LEP. Particular emphasis has been given to the particles (Higgs
