Dynamical electroweak symmetry breaking with large anomalous dimension and t quark condensate
Abstract
A new class of models with dynamical electroweak symmetry breaking is proposed. In these models the composite operator overlineψψ 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^{2}θ _{w}≅1 . The scenario naturally leads to a large value of the t quark mass.
