| Outline of Final Research Achievements |
In order to search for unknown particle models beyond the Standard Model, a theoretical framework using effective interactions in the TeV energy scale region is developed. In particular, we theoretically analyze the production and decay processes of new particles in the LHC experiment and discuss the feasibility of the search for the case with two heavy partners of the top quark, satisfying the constraints arising from various existing experiments. The same concept of effective interaction is applied to the precise measurement of the Higgs boson, which contributes to clarifying the scientific implications of the future ILC experiment.

| Academic Significance and Societal Importance of the Research Achievements |
素粒子標準模型を超える素粒子模型を探ることは、現代の素粒子物理学で最も重要な課題である。ＬＨＣ実験や将来のＩＬＣ実験などのエネルギーフロンティア実験により、ヒッグスセクターや重いクォークセクターを通じて、素粒子の世界の自然法則と宇宙初期の謎を解明を目指すことは、最も基本的なアプローチと言える。この研究成果は、その有効性を示す例として、学術的意義がある。
