Abstract
We have carried out numerical studies of vacuum alignment in technicolor models of electroweak and flavor symmetry breaking. The goal is to understand alignment’s implications for strong and weak CP nonconservation in quark interactions. In this first part, we restrict our attention to the technifermion sector of simple models. We find several interesting phenomena, including (1) the possibility that all observable phases in the technifermions’ unitary vacuum–alignment matrix are integer multiples of π/N where N ≤ N, the number of technifermion doublets, and (2) the possibility of exceptionally light pseudoGoldstone technipions.
