Outline of Final Research Achievements

In this research, we aim at searching for new physics beyond the standard model in decays of B mesons and tau leptons at the SuperKEKB/Belle II experiment. We also aim at a precise measurement of the muon g-2/EDM at J-PARC. During the term of this research, we obtained results of lepton universality test in the weak decay of B mesons from data taken in the early runs of Belle II. We also obtained the result of the electron- positron collision cross sections, which is an important input to evaluate the muon g-2 value in the standard model. We have established the performance of the TOP counter and aerogel RICH detector, which we developed based on our original idea, and developed new photosensors for further performance improvement. For the J-PARC experiment, we developed an ultra-slow muon source and a beam monitor, by transferring the technology originally developed for the Belle II experiment.

Academic Significance and Societal Importance of the Research Achievements

世界中で標準理論を超える新物理の探究が進むなか、B崩壊におけるレプトン普遍性やミューオンg-2の理論予言値からの乖離は、「フレーバーアノマリー」と呼ばれる喫緊の課題であり、本研究は、この課題解決に向けた重要なステップとなる。Belle II実験では、初期データながらも先行実験に匹敵する精度の結果が得られ、今後のデータ蓄積により高精度測定が可能なことを示した。確立された粒子識別装置に関連する技術は、新しいトレンドとして他実験での使用が検討されている。本研究による冷却ミューオン源とビームモニタの開発や他の科研費等で進めた研究によって、J-PARCミューオンg-2/EDMの実施が大きく前進した。
