| Research Abstract |
Higher dimensional gauge theory, namely the gauge-Higgs unification is an attractive candidate for solving the problem related to the Higgs particle in the standard model. In this research we studied the dynamics possessed by the higher dimensional gauge theory both from a perturbative and nonperturbative point of view. In particular, we obtained the unexpected result that gauge symmetry can be broken even at high temperature. We studied higher dimensional gauge theory on lattice and found the new symmetry called stick symmetry inthe theory, which plays an important role to construct low-energy effective theory and to perform numerical simulation. Moreover, we also discussed the application of the gauge-Higgs unification to grand unified theory.
