Outline of Final Research Achievements

We construct many models to unify three geneations of quarks and leptons based on the gauge theory on 6-dimensional space-time including an orbifold as an extra space. We study the magnitude of D-component in a generic supersymmetric gauge field theory and obtain inequalities relating F and D-components. We propose a model to realize the unification of gauge couplings at the Planck scale in the presence of extra particles around the terascale, as a physics beyond the standard model. We propose a new solution to the quadratic divergence problem concerning the Higgs boson mass, using the idea that unnaturalness would be improved if features of an ultimate theory are taken in.
