Composite technicolor standard models
In this thesis we introduce the idea of Composite Technicolor Standard Models (CTSM). In these models the quarks, leptons, and technifermions are assumed to be composite particles built from fermions (preons) bound by strong gauge interactions. We argue that if the preon dynamics respects an (SU(3) {times} U(1)){sup 5} flavor symmetry that is explicitly broken only by preon mass terms which are proportional to the quark and lepton mass matrices, then the theory as a natural GIM mechanism which suppresses dangerous flavor changing neutral currents. We show that CTSM effects give rise to a number of small, but observable, deviations from the standard model of electroweak interactions. We discuss the difficulties with anomaly constraints and flavor symmetry breaking involved in building a Composite Technicolor Standard Model. We conclude by constructing a model of quarks with the required symmetry properties.
