我们报道了在中国锦屏地下实验室进行的CDEX-10实验的第一个结果,该实验使用一个10公斤的锗探测器阵列浸泡在液氮中,物理数据大小为102.8公斤 天。在160℃的分析阈值下,在WIMP质量为()的自旋无关和自旋相关的WIMP核子截面上,分别获得了改进的极限和90%的置信度水平。的下游延伸到了。
We report the first results of a light weakly interacting massive particles (WIMPs) search from the CDEX-10 experiment with a 10 kg germanium detector array immersed in liquid nitrogen at the China Jinping Underground Laboratory with a physics data size of 102.8 kg day. At an analysis threshold of 160 eVee, improved limits ofandat a 90% confidence level on spin-independent and spin-dependent WIMP-nucleon cross sections, respectively, at a WIMP mass () ofare achieved. The lower reach ofis extended to.
