Research Abstract

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.
