抄録/ポイント： nEXOニュートリノレス二重ベータ(0νββ)減衰実験を,136Xeにおける減衰を探索するために,時間投影チャンバと5000kgの同位体濃縮液体キセノンを使用するように設計した。検出器設計の進歩は,EXO-200の最終結果に使われたものに基づく,そのシミュレーションにおけるより高い忠実度と,先進的データ解析と対して,1028年の半減期を超える感度予測を生成する。特に,シンチレーション光子と電荷の生成および検出器における輸送と再構成の理解において改善がなされた。検出器構築のより詳細な知識は,異なる材料中の微量放射能に対するより多くのアッセイと対になった。特に,カスタム電鋳銅の使用を設計に組み込み,検出器材料の固有放射能からバックグラウンドを大幅に削減する。さらに,以前の感度予測からの多くの仮定は,nEXO実験概念を検証する中間作業からのさらなるサポートを得た。これらの改良と更新は,nEXO実験が,ほぼ全ての核マトリックス要素に対して,正規秩序シナリオに対するパラメータ空間のかなりの部分と共に,逆ニュートリノ質量秩序化に関連したパラメータ空間をカバーする,データ取得の10年において,90%信頼レベルで1.35×1028年の半減期感度に達することを示唆する。射影に用いた名目値から逸脱するバックグラウンドの効果も説明し,nEXO設計がモデルの多くの不完全性に対してロバストであると結論した。Please refer to the publisher for the copyright holders.
