Dynamical Symmetry Breaking with Large Anomalous Dimension in Gauge Theories

Abstract

An analysis is given of the dynamical symmetry breaking of semi-simple gauge groups. We construct a class of renormalizable gauge theories for the dynamically broken topcolor and technicolor interactions. It is shown that a four-Fermi interaction in the strong coupling phase emerges by the tumbling of semi-simple gauge groups in the low energy region. In our models the topcolor interaction provides the top quark with a large anomalous dimension.
