低温暗物质搜索低电离阈值实验 (CDMSlite) 实现了对其锗靶中非常小的反冲能量的有效检测，从而在先前未探索的电荷、质量和速度参数空间区域中实现了对轻电离粒子 (LIP) 的敏感性。我们报告了使用最佳间隔方法计算出的第一个直接检测极限，计算出电荷小于 e=(3 x 10(5)) 的宇宙产生的 LIP 的垂直强度，以及电荷的最强极限
The Cryogenic Dark Matter Search low ionization threshold experiment (CDMSlite) achieved efficient detection of very small recoil energies in its germanium target, resulting in sensitivity to lightly ionizing particles (LIPs) in a previously unexplored region of charge, mass, and velocity parameter space. We report first direct-detection limits calculated using the optimum interval method on the vertical intensity of cosmogenically produced LIPs with an electric charge smaller than e=(3 x 10(5)), as well as the strongest limits for charge
