Outline of Final Research Achievements

We have studied the physics relevant to the Higgs self-coupling constant
in order to probe the Higgs boson self-interactions. (1) We have explored the method to extract the information of the Higgs boson self-coupling
in the single Higgs production processes by focusing the radiative corrections and the dispersion relations. (2) We have investigated the gravitational wave signal of the scalar self-interactions of the hidden sector, which also triggers the electroweak symmetry breaking. (3) We have constructed a neutrino mass model originated from the strongly self-interacting scalar dark matter.

Academic Significance and Societal Importance of the Research Achievements

ヒッグスボソンの発見により素粒子標準模型は一応の完成をみたが, 「なぜ電弱対称性が破れたか?なぜ電弱スケールがプランクスケールに比べて小さいのか」などの問題が手付かずに残った.
ヒッグスボソンとその背後の物理を探るために, すなわち電弱対称性の破れの起源の解明するために,
ヒッグス自己結合の検証方法を確立することが必要である.
