Outline of Final Research Achievements

Our research has three themes: bottom-up research based on the elucidation of new electroweak physics, top-down research based on superstring theory, and research on the evolutionary history of the universe based on new physics, through which we aim to deepen our understanding of space-time.
As a specific research achievement, we completed the first ever detailed calculation of the decay rate of the electroweak vacuum in the Standard Model. Research was conducted on methods to search for and verify supersymmetric particles in future accelerator experiments. We also studied a model that derives the electroweak scale from the Planck scale by considering stationary solutions of superstring theory with a rotating D-brane system. Furthermore, we clarified the consistency of long-lived unstable particles appearing in the new physics with the Big Bang elemental synthesis scenario.

Academic Significance and Societal Importance of the Research Achievements

LHCにおけるヒッグス粒子の発見により素粒子の標準模型は完成したものの、標準模型は理論的には不自然な理論と考えられ、新物理の存在が期待される。また宇宙論に目を向ければ暗黒物質の存在など標準模型を超える物理の存在が示唆されている。本研究では、新物理に対して、素粒子物理学、超弦理論、宇宙論など多角的な観点から、新物理がどのこれらの分野にどのような帰結をもたらすか研究を進めてきた。LHC等の実験によりまだ新物理は発見されていないが、本研究の成果は新物理に制限を与えるとともに、将来の新物理の発見がもたらす宇宙発展や時空の理解へ貢献することが期待される。
