Model building on a coset space

我研究了具有额外维度的协集空间结构的理论，以构建一个超越标准模型的模型。我用了两种方法。一是我利用协集空间降维（Coset Space Dimensional Reduction， CSDR）的方法探索可行的模型，这些模型在CSDR之后被降维为标准模型。另一个是我在S2上构建模型S2是最简单的余集空间。一个模型是具有SO（12）规范群的统一理论。另一种是利用通用额外维度模型（Universal Extra Dimensional Model， UED）的思想，将标准模型扩展为S2额外维度模型。现在两种模式都证明是可行的。

I studied theories with extra dimensions of coset space structure to construct a model beyond the Standard Model. I employed two methods for it. One is that I explored viable models using the method of Coset Space Dimensional Reduction (CSDR) which are reduced to the standard model after CSDR. The other is that I constructed models on S2 which is the simplest coset space. One model is a unified theory with SO(12) gauge group. The other is by employing the idea of Universal Extra Dimensional Model (UED) I extended the Standard Model to S2 UED Model. Both models are shown to be viable now.
