Abstract

We propose a model where the role of the electroweak Higgs field is played by the dilaton. The model contains terms which explicitly violate gauge invariance; however, it is shown that this violation is fictitious, so that the model is a consistent low-energy effective theory. In the simplest version of the idea the resulting low-energy effective theory is the same as the top mode standard model.
