INFRARED ANOMALOUS INTERACTIONS AS A SIGNAL FOR ELECTROWEAK SYMMETRY BREAKING BY COLOR SEXTET QUARKS

Abstract

We study the possibility that electroweak symmetry breaking occurs dynamically as a consequence of a chiral condensate of color sextet quarks. New (but conventional) leptons are used to cancel gauge anomalies. An effective Lagrangian with a Wess-Zumino term is used to describe “sextet pion” interactions and associated chiral anomalies. We show that the gauge-invariant effective Lagrangian which describes infrared interactions of the physical W± and Z0 vector bosons contain axial-vector chiral anomalies generated by lepton loops. Lepton-induced anomalous interactions would therefore be a signal of this form of dynamical symmetry breaking.
