当人们穿越相互作用的参数空间竞争对齐真空时,会发生重复的破坏和恢复相变。这种现象,加上类似顶色的相互作用,可以使复合希格斯玻色子的质量和真空期望值自然地远小于其潜在的结构尺度,而不会引入新的对称性及其相关的TeV尺度粒子。我们通过重建Georgi和Kaplan提出的一个简单的电弱对称破缺的轻复合希格斯模型来说明这一点。
Repeated symmetry-breaking and restoration phase transitions occur as one traverses the parameter space of interactions competing to align the vacuum. This phenomenon, augmented with a topcolor-like interaction, can make a composite Higgs boson's mass and vacuum expectation value naturally much less than its underlying structure scale, without introducing new symmetries and their associated TeV-scale particles. We illustrate it by reconstructing a simple light composite Higgs model of electroweak symmetry breaking proposed by Georgi and Kaplan.
