Abstract
A linear realization of a model of dynamical electroweak symmetry brea king describing additional heavy vector bosons is proposed. The model is a SU(2)(L)xU(1)xSU(2)(L)'xSU(2)(R)' gauge theory, breaking at some high scale u to SU(2)(weak)xU(1)(Y) and breaking again in the standard way at the electroweak scale upsilon to U(1)(em). The model is renorm alizable and reproduces the standard model in the limit u --> infinity . This decoupling property is shown to hold also at the level of radia tive corrections by computing, in particular, the epsilon parameters.
