摘要
CDMSlite 运行 2 是一项利用 600 g 低温 Ge 探测器以高压模式运行来搜寻弱相互作用大质量粒子（WIMPs）的实验，该模式优化了其对 2 - 20 GeV/ 相对低质量 WIMPs 的灵敏度。在本文中，我们利用扩展的能量范围和对预期本底的全面处理，对 CDMSlite 运行 2 数据进行了有效场论（EFT）分析。对反冲能量数据进行了分箱似然贝叶斯分析，考虑了 EFT 相互作用的参数并针对主要本底成分优化数据选择。分析中移除了已知活化峰 5 范围内的能量区域。由不同算符假设得出的贝叶斯证据显示，CDMSlite 运行 2 数据与仅本底模型一致，且不允许在假设任何额外 EFT 相互作用下进行信号解释。因此，针对每个 EFT 算符给出了 WIMP 质量与耦合系数振幅及相位的上限。这些限制在 WIMP 质量高于 5 GeV/ 时改进了先前的 CDMSlite 运行 2 界限。
