Outline of Research at the Start

KamLAND-Zen800の主要バックグラウンドである宇宙線起源の10Cを低減する新型電子回路を開発・導入する。観測停止期間を最小限にする導入で高い稼働率を維持し、期間内に逆階層構造に切り込み複数の理論モデルを検証できる40meVをきる探索感度を実現する。逆階層構造をカバーする20meVに達する感度実現のための開発も並行する。また、極低放射能を究める上で必須なスクリーニング環境も構築し、領域内やコミュニティでの共有化を図る。さらに地球ニュートリノ観測では、原子炉ニュートリノの影響が少ないデータで観測精度を向上し、宇宙の化学進化到達点の直接的な観測により、宇宙の物質進化解明を推進する。

Outline of Final Research Achievements

We conducted a search for neutrinoless double beta decay in 136Xe with the world's highest sensitivity. The energy resolution was improved through detailed calibration and improved analysis methods, and the problem of the generation of long-lived radioactive nuclei due to cosmic rays was reduced by focusing on the number of associating neutrons. As a result, the excluded region on effective Majorana neutrino mass reached the inverted ordering region for the first time in the world, and started to cover theoretical predictions. Furthermore, in the geoneutrino observations that were being carried out in parallel as a multipurpose project, we succeeded in eliminating the High-Q model, which has a large amount of geothermal heat, and succeeded in providing new knowledge about the convection style and composition of the mantle. Neutrino observation has reached a new milestone in solving major problems in earth science.

Academic Significance and Societal Importance of the Research Achievements

排除領域が逆階層領域や理論予想に切り込み始めたことで、「宇宙物質優勢の謎」といった根源的な疑問を解明できる可能性が一気に高まった。これを受け世界の探索計画は逆階層領域のカバーという方針に転換され、国際協働による統合や淘汰が進み、分野全体の底上げにつながった。また、地球ニュートリノ研究が地球科学に新たな知見をもたらし始めたことで、さらに挑戦的な観測プロジェクトが素粒子・地球科学の協働で提案されるなど、学際分野の活性化が進んだ。これら、知的好奇心を喚起するテーマにおいて世界をリードする研究を国内で進行させることで、優秀な若手の興味を引きつけ、科学立国日本の将来を担う人材発掘や育成に貢献した。
