Outline of Research at the Start

日本がホストするスーパーBファクトリー（SuperKEKB/Belle II）実験に関して、国内外の実験-加速器-理論の研究グループ間の強固な連携により、同実験の衝突性能と物理探索能力を究極的に高め、標準理論を超える物理の発見を目指す。そのために、国内外の研究機関の間での双方向の研究交流や人材還流を強化して、KEKでの実験遂行と地球規模での機器開発や物理研究を進める。以上の研究をとおして、将来の国際共同加速器プロジェクトをリードする人材を育成する。

Outline of Annual Research Achievements

本研究は、スーパーBファクトリー（SuperKEKB/Belle II）実験を舞台として、国内外の実験-理論-加速器の強固な連携により、同実験の衝突性能と物理探索能力を究極的に高め、標準理論を超える物理の発見を目指している。
2024年度には、前年度2024年1月から12月までの運転期間中に、世界最高衝突性能の更新（ピークルミノシティ=5.1x1034cm-2s-1）と、積分ルミノシティ=575fb-1相当のデータ蓄積を達成し、これと機械学習等を導入したデータ解析により従来を上回る精度・感度でB中間子やタウレプトンの崩壊測定が可能となった。また、2023年度秋までの長期運転停止期間（LS1）に入れ替えたBelle II崩壊点検出器や新規コリメータなどの装置が正常に機能することを確かめた。一方で、突発的なビーム損失現象（SBL: Sudden Beam Loss）が依然として頻発したが、2024年12月までの運転で、その有力な原因を突き止めた。この過程では、本研究で強化した加速器-実験研究者との連携研究、物理解析や加速器運転への機械学習の応用研究が大きく寄与している。
物理成果としては、暗黒物質の候補となる軽い新粒子の探索、ミューオン異常磁気能率の検証に重要となる電子-陽電子衝突断面積測定、B中間子崩壊におけるCP対称性の破れ、小林-益川行列要素の測定、レプトン普遍性の検証に関する初期データによる結果導出を進めた。特に、B中間子がK中間子とニュートリノ対に崩壊する稀崩壊過程（B→Kνν）の証拠を世界に先駆けて発見し、B中間子のセミレプトニック崩壊におけるレプトン普遍性の検証、電子-陽電子衝突断面積測定に関するBelle II実験の最初の重要な結果を論文として公表した。
これらの実験遂行やデータ解析の推進は国際共同で進み、本科研費研究に参画する若手研究者が大きく貢献している。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

SuperKEKB/Belle II実験では、世界最高衝突性能の更新と、積分ルミノシティ=575fb-1相当のデータ蓄積を達成し、これと機械学習等を導入したデータ解析の工夫により従来を上回る精度、好感度でB中間子やタウレプトンの崩壊測定が可能となり、2024年度中に26編の論文を公表できた。また、LS1中に入れ替えた崩壊点検出器や新規コリメータなどが正常に機能することを確かめた。
一方で、突発的なビーム損失現象（SBL: Sudden Beam Loss）が依然として頻発し、データ直積が当初の予定どおりには進んでいない。しかしながら、本研究によって実験と加速器の連携が大きく進み、ビーム診断に必要となるモニター類の強化、機械学習による加速器運転の自動制御などの研究が進み、これとデータ解析への機械学習の積極的な導入などにより、、従来の結果に匹敵あるいはそれを上回る精度・感度での多くのデータ解析結果が得られている。研究実績概要に記したB→Kνν崩壊の証拠発見や、B中間子のセミレプトニック崩壊におけるレプトン普遍性の検証結果導出はその好例である。
以上の研究を国際共同で進めるために、実験、加速器、理論の若手研究者を海外研究機関に派遣した。今後の装置アップグレードに向けて、崩壊点検出器に関連してはフランス・ドイツ、粒子識別装置に関してスロベニア、加速器ルミノシティ改善に関して米国、データ解析に関してフランス、理論研究に関してはスイスへ数ヶ月の派遣を行い、今後、より本格的な国際共同研究とその中での人材育成を進めることができると考えている。

Strategy for Future Research Activity

2025年度の研究計画としては、SuperKEKB/Belle II実験の運転を秋から再開し、1×10^35cm-2s-1の衝突性能と世界最高となる1ab^-1を超える衝突データの蓄積を目指す。これにより、従来の実験結果を上回る精度・感度での結果導出を図る。実験と理論が連携して、同実験でB中間子とともに大量に生成されるタウレプトンの崩壊測定による新物理探索に関するワー
クショップ等を開催して、得られたデータ解析結果の解釈や、今後のデータ解析の方針を議論する。先行実験の数倍のデータが収集できた段階で、B崩壊に関する精密測定結果を導出し、最終的には、実験-理論の共同解析により、BSMの兆候を見出すあるいはそのモデルに制限をつける共同解析を進めてゆく。
中長期的には、将来に予定しているLS2（Long Shutdown 2）での加速器と測定器のアップグレードの概念設計、必要となる技術開発を海外研究機関との連携を強化して進める。具体定には、CMOSピクセルを用いた新しい崩壊点検出器（フランス、ドイツ）、粒子識別装置の性能改良（スロベニア、イタリア）、加速器ルミノシティ改善のための装置開発（米国）、理論研究（スイス）などがある。また、データ解析だけでなく装置運転への機械学習の応用に関する共同研究の強化を進める。
こうした研究推進のために、2023年度から進めているポスドク雇用、海外若手派遣、国内インターンシップ（RA）、若手プロジェクト研究などの人材育成プログラムを継続して進め、若手研究者が、国際共同研究の中で、修士課程ー＞博士課程ー＞ポスドクとステップアップしてゆけるように導き、支援を行ってゆく。
