【摘要】：暗物质探测已成为当今科学最重要的课题之一。弱相互作用重粒子(weakly interacting massive particles,WIMPs)是众多理论模型中最有可能的暗物质候选者之一。暗物质直接探测原理是:WIMPs与地面探测器的靶核通过弱相互作用,发生弹性散射,反冲核被弹出,探测器将反冲核能量记录下来,得到暗物质与探测器相互作用的信号。文章介绍了国际上主流的暗物质直接探测的方法、现状以及未来直接探测的路线。还介绍了世界最深地下实验室——中国锦屏地下实验室的现状和二期扩建情况。文章最后详细介绍了中国暗物质合作组的研究历程、探测技术、研究取得的成果和未来规划。
[Abstract]:Dark matter detection has become one of the most important subjects in science. Weakly interacting heavy particle (weakly interacting massive particles,WIMPs) is one of the most likely candidates for dark matter in many theoretical models. The principle of direct detection of dark matter is that elastic scattering occurs through weak interaction between the WIMPs and the target nucleus of the ground detector, and the recoil nucleus is ejected. The detector records the energy of the recoil nucleus and obtains the signal of interaction between the dark matter and the detector. This paper introduces the direct detection methods of dark matter in the world, the present situation and the route of direct detection in the future. The present situation of the world's deepest underground laboratory, Jinping underground laboratory in China, and the second phase expansion of the laboratory are also introduced. In the end, the research process, detection technology, research results and future planning of China dark matter cooperative group are introduced in detail.
