Outline of Final Research Achievements

My project is mainly about extending the physics potential of the T2K and T2HK neutrino oscillation experiment in Japan. This two experiments uses the neutrino oscillation to measure the neutrino CP phase. However, these two experiments are designed for discovery, namely, whether the neutrino CP phase is zero or not. But they are not good at measuring the value of the neutrino CP phase precisely due to some intrinsic design issues. Together with some colleagues, I proposed the TNT2K experiment by adding a new low energy neutrino source in Toyama county around the Kamioka experiment site. My current project extended the physics potential of this TNT2K experiment by allowing it to measure more interesting phenomena in neutrino oscillation. Then, the TNT2K experiment can do multi-purpose measurement to make the largest outcome. My study shows that this new TNT2K design is an optimal design for future upgrade of the existing neutrino experiments in Japan.

Academic Significance and Societal Importance of the Research Achievements

我々の宇宙は、反物質ではなく物質で構成されている。物質と反物質の量は、宇宙の初期では全く同じである。物質と反物質のペアは、対で生成および消滅をすることができる。しかし現在、私たちの宇宙には物質のみで反物質は見られない。この事実に対して、日本の物理学者の柳田勉と福来正孝はレプトン生成を可能な説明として提案した。その鍵となる要素のニュートリノのCP位相は、物質と反物質の違いを指し示す。T2K / T2HKと比較して、TNT2K実験ははるかに正確な測定を行うことができる。私のプロジェクトは、TNT2K実験における物理の可能性をさらに拡げ、TNT2K実験をより魅力的なものにするのに役立つものである。
