Dynamical Electroweak Breaking: Issues and Challenges
Abstract
After briefly remarking on alternatives for breaking the electroweak symmetry, I discuss the implication that recent precision experiments at LEP have for the symmetry breaking sector. The difficulties associated with generating fermion masses when the electroweak symmetry is broken dynamically are exposed and an alternative to the walking technicolor - extended technicolor scenario is suggested, based on models of substructure. Failures and lessons from trying to incorporate families and mixing in these latter schemes are also discussed.
