【摘要】：暗物質(zhì)探測已成為當(dāng)今科學(xué)最重要的課題之一。弱相互作用重粒子(weakly interacting massive particles,WIMPs)是眾多理論模型中最有可能的暗物質(zhì)候選者之一。暗物質(zhì)直接探測原理是:WIMPs與地面探測器的靶核通過弱相互作用,發(fā)生彈性散射,反沖核被彈出,探測器將反沖核能量記錄下來,得到暗物質(zhì)與探測器相互作用的信號。文章介紹了國際上主流的暗物質(zhì)直接探測的方法、現(xiàn)狀以及未來直接探測的路線。還介紹了世界最深地下實驗室——中國錦屏地下實驗室的現(xiàn)狀和二期擴建情況。文章最后詳細(xì)介紹了中國暗物質(zhì)合作組的研究歷程、探測技術(shù)、研究取得的成果和未來規(guī)劃。
[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.
