【摘要】：评述了天体物理中暗物质的发现以及标准模型所面临的问题,综述了解决这些问题及标准模型之外可能出现的新物理与暗物质的联系。介绍了暗物质粒子选择条件和可能的暗物质粒子的候选者;对圆柱形暗物质表面密度与星系和星系团暗物质晕的晕核半径的关系进行了讨论,与其他模型进行了比较,得出暗物质晕的特征半径r?的暗物质表面密度分布不是一个普适量;并叙述了近几年暗物质研究中提出的新理论模型-Hidden dark matter,最后叙述了中国暗物质实验探测研究的进展,2016年底DAMPE的第一批数据有可能给出;中国锦屏地下实验室(CJPL)的CDEX和Panda X合作组的第一期实验没有发现暗物质粒子存在的信号,期待他们下期的实验。
[Abstract]:The discovery of dark matter in astrophysics and the problems faced by standard models are reviewed. In this paper, the relationship between new physics and dark matter which may appear outside the standard model is reviewed. The selection conditions of dark matter particles and the possible candidates for dark matter particles are introduced. The relationship between the surface density of cylindrical dark matter and the radius of halo nuclei of galaxies and clusters of dark matter halos is discussed, and compared with other models, the characteristic radius of dark matter halo is obtained. The surface density distribution of dark matter is not a normal amount; In this paper, a new theoretical model, named Hidden dark matter, which has been put forward in dark matter research in recent years, is described. Finally, the progress of experimental detection of dark matter in China is described. In end of 2016, DAMPE's first batch of data is likely to be given; The first phase of the CDEX and Panda X collaboration group at China's Jinping Underground Laboratory found no signals of the presence of dark matter particles and are looking forward to their next experiment.
