摘要
地中海下一代水切伦科夫中微子望远镜正在法国近海（KM3NeT/ORCA）和西西里（KM3NeT/ARCA）建设。KM3NeT/ORCA 探测器的能量探测阈值允许收集大气中微子以研究味振荡。本文报道 KM3NeT/ORCA 对此现象的灵敏度。描述了事件重建、选择与分类。评估了确定中微子质量顺序的灵敏度，发现在取数三年后，若真实顺序为正序则为 4.4 ，若为真序则为 2.3 。对 和 的测量精度也进行了估计，正序中微子质量顺序下为 eV 和 ，反序下为 eV 和 。最后，描述了通过测量 tau 中微子产额对轻子混合矩阵进行的幺正性检验。发现三年取数足以在 水平排除大于 20% 的 和 事件率变化。
