The purpose of this talk is to show what sort of dynamics are needed in order to render such theories phenomenologically viable.Talk given at the Corfu Summer Institute on Elementary Particle Physics, September 1998, to appear in the proceedingsHigh Energy Physics - PhenomenologyDynamical symmetry breaking with mirror fermionstext
