Research Abstract

I investigated models with extra dimensions as a candidate for the theory beyond the standard model in particle physics. Especially, I focus on the breaking of the electroweak gauge symmetry and the supersymmetry. For the former, I clarified the relation between the Higgs particle and the radion, which is a particle related to the stabilization of the extra dimension, in the context of the gauge -Higgs unification models. For the latter, I developed useful formulation of five-dimensional supergravity. This makes it possible to discuss various models based on the five -dimensional supergravity much easier.
