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 γm≅2 and the t quark plays an important role in the generation of W and Z boson masses without destroying the relation {M W2}/{M Z2}cos2θ w≅1 . The scenario naturally leads to a large value of the t quark mass.
