Abstract
A new class of models with dynamical electroweak symmetry breaking is proposed. In these models the composite operator ψψ has a large anomalous dimension γ m ≅2 and the t quark plays an important role in the generation of W and Z boson masses without destroying the relation M W 2 M Z 2 cos 2θ w ≅1 . The scenario naturally leads to a large value of the t quark mass.
