摘要
位于法国 Modane 地下实验室（Laboratoire Souterrain de Modane）的 CUPID-Mo 实验是下一代吨级低温 实验 CUPID 的验证装置。它由 20 个富集的 LiMoO 闪烁热量计组成、总质量 4.2 kg，用于搜寻 Mo 中破坏轻子数的 衰变过程。经过一年多运行（2.16 kgyr 物理数据），在感兴趣区域内未观测到任何事件，因此没有 的证据。我们报告了 Mo 中 衰变半衰期的新限值：yr（90% 置信区间）。该限值对应于轻 Majorana 中微子交换解释下有效 Majorana 中微子质量 (0.31--0.54)eV，具体取决于核矩阵元。
