研究テーマ

高エネルギー物理学・素粒子実験

• つくば市にある高エネルギー加速器研究機構(KEK)で行われているBelle実験・Belle II実験グループに参加して、素粒子の性質を調べている。Belle実験は、KEKB 加速器（電子、陽電子衝突型加速器）で、作り出された大量のB中間子と反中間子をBelle測定器を使うことで、その性質の違いを主に調べている実験です。加速器や検出器をアップグレードしたBelle II実験に参加し、シミュレーション用のMCサンプル作成やGRIDコンピューティングに関する研究(DCグループ)で貢献しています。
• 欧州・北米・アジア諸国とともに計画されている国際リニアコライダー実験計画(ILC実験)の実現へ向け、検出器グループの一つILDグループに参加し、シミュレーション解析のためのMCサンプル作成の責任者として貢献する他，カロリメータの開発(CALICEグループ)、ヒッグス粒子の精密測定に関する基礎研究を国際協力の下で行っている。
• 新型素材を用いた安価なプラスチックシンチレータの研究開発を新潟大学理学部物理学高エネルギー研究室・カーリットホールディングス(株)と共同で行っており，ニュートリノを用いた小型原子炉出力モニターへの応用を目標としている。
