Description
The theoretical origin of the Higgs boson remains unclear. Yang-Mills theories in higher dimensions are good candidates to address this issue.
We have constructed a Yang-Mills theory with extra dimensions of two-dimensional sphere. In this model, compared to conventional models such as those with S^1 and T^2, curvature of the extra dimensions and the non-commutative nature of the gauge group result in different features in gauge symmetry breaking process and the origin of scalar fields.
In this talk, we will report the mass spectrum obtained from the Kaluza-Klein expansion of the gauge field components in the extra dimensions, which appear as scalar fields in our four-dimensional spacetime.
