我们在电弱和味对称破缺的彩色模型中进行了真空对准的数值研究。目标是了解在夸克相互作用中强和弱CP不守恒的排列含义。在第一部分中，我们将注意力限制在简单模型的技术领域。我们发现了几个有趣的现象，包括(1)technifermions的酉真空排列矩阵中所有可观测相都是{pi}/N{sup '}（其中N{sup '}{<=}N）的整数倍的可能性，technifermions双重态的数量，以及(2)异常轻的伪Goldstone技术的可能性。(c) 2000年美国物理学会。
We have carried out numerical studies of vacuum alignment in technicolor models of electroweak and flavor symmetry breaking. The goal is to understand alignment 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 {pi}/N{sup '} where N{sup '}{<=}N, the number of technifermion doublets, and (2) the possibility of exceptionally light pseudo Goldstone technipions.
