Phenomenological and Theoretical Aspects of Effective Gauge Theories
The first part of this thesis examines the lightest non-standard particles occurring in technicolor theories, namely the pseudo-Goldstone bosons of technicolor chiral symmetry breaking, and their couplings to the Z particle. Such couplings may be of experimental importance in discovering pseudo-Goldstone bosons and distinguishing them from the scalar particles occurring in other schemes of electroweak symmetry breaking. In the second part of the thesis I try to formulate in a simple and precise way the notion of an 'effective chiral gauge theory'. This is important since most effective particle theories are gauge theories, and at least because of the need to incorporate the electroweak theory, they are chiral gauge theories. I provide a formally non-perturbative, but perturbatively realized gauge invariant regularization for the matter fields of chiral gauge theories.
