Outline of Final Research Achievements

We have studied the origin of dark matter, baryon asymmetry in the universe and the origin of the electroweak scale of unsolved problems in the Standard Model of particle physics from the viewpoint of gauge-Higgs unification model as one of the extension of the Standard Model.
On the dark matter, we have shown that Majorana fermion with a half of Higgs mass and the first Kaluza-Klein mode of the gauge field with same quantum number as Higgs field could be a dark matter. On baryogenesis, a possibility of electroweak baryogenesis has been analyzed. As a result, it was turned out that the temperature where baryon is generated is lower comparing to the weak scale, which implies a requirement for corrections of our model. In models of magnetic flux compactification, the electroweak scale can be derived even if the new physics scale is Planck scale. We have succeeded in reproducing fermion mass hierarchy in grand gauge-Higgs unification.

Academic Significance and Societal Importance of the Research Achievements

素粒子物理、宇宙物理の謎である暗黒物質の起源について、素粒子に質量を与えるヒッグス場と電弱力を伝えるゲージ場を高次元時空で統一する模型の枠組みで、候補の1つを示せたことは意義があり、暗黒物質探索実験において発見される可能性を残した。標準模型を超える新物理の兆候がない現状に鑑み、新物理スケールがプランクスケールのような高いスケールの場合でも、余剰空間に磁場が入る場合は、電弱対称性のスケールが自然に導出できる可能性があり、新物理の新たなアプローチを提供するインパクトが期待される。
