Dynamical Electro-Weak Symmetry Breaking with a Standard Model Limit

Abstract

We argue that a Standard Model decoupling limit is generically the necessary ingredient which makes scenarios of electro-weak symmetry breaking viable. This applies especially also to models of dynamical electro-weak symmetry breaking. Additional requirements are only that the mass predictions of a given model (e.g. predictions or theoretical limits on the Higgs or top mass) are consistent with existing data. We discuss the necessary ingredients for dynamical symmetry breaking and present a dynamically broken left-right-symmetric model as an example. The model exhibits such a decoupling limit, is phenomenologically viable and leads to interesting mass predictions and relations which are further examined.
