Deconstructed extra dimensions and the electroweak symmetry breaking particle phenomenology

基本粒子质量的起源背后隐藏着什么物理学原理？希格斯势导致了标准模型中的等级问题，因此在理论上是不能令人满意的。在解构的额外维度框架下，我们探讨了“无希格斯”理论的可能性，即在不引入希格斯标量粒子的情况下实现电弱对称性破缺。结果明确表明，该模型的构建与电弱和风味精度测试一致。我们还讨论了在这种模型中纵向规范玻色子散射的结构和对撞机现象。这些结果在经过评审的期刊论文和国际会议上作了报告。

What is the physics hidden behind the origin of elementary particle masses? The Higgs potential causes the hierarchy problem in the Standard Model and it is therefore theoretically unsatisfactory. We explored the possibility of "Higgsless" theories, achieving the electroweak symmetry breaking without invoking an Higgs scalar particle, in the deconstructed extra dimension framework. It was explicitly demonstrated that such a model can be constructed consistently with the electroweak and flavor precision tests. We also discussed the structure of the longitudinal gauge boson scattering and the collider phenomenology in such a model. These results were reported in refereed jounal papers and at international conferences.
