Outline of Final Research Achievements

Our Universe came into existence through explosive expansion of a microscopic universe 13.8 billion years ago. This research project studied the Grand Unified Theories (GUTs) which are the key to understanding the explosive expansion. We lead an international research team to search for a muon’s rare decay as evidence of the GUTs by exploiting the world’s highest-intensity muon beam in Switzerland. We discovered that the decay only occurs at a rate less than one per 2 trillions, which strongly constrains the general framework of the GUTs. We also successfully realized experimental apparatus that has 10 times higher sensitivity. It is expected that 4-5 years of data taking could lead to a discovery of the decay and thus evidence of the GUTs.

Academic Significance and Societal Importance of the Research Achievements

宇宙がどうしてビッグバンから始まったのか、その謎を解く鍵となる大統一理論を検証することは、未だ知られていない物理法則の探究と宇宙論の発展に直接つながると共に、人類を産んだ宇宙の起源に迫ることになり、その文化的意義も高いと考えられる。また、究極感度の実験を実現するために新しく開発した粒子測定技術は、暗黒物質探索などの宇宙物理研究や放射線を使ったPETなどの医療診断装置などへの応用が検討されている。
