暗物质属性的研究是当前粒子物理和宇宙学的前沿课题。本项目密切结合暗物质的空间间接探测和地下直接探测的实验结果，开展暗物质与相关超出粒子物理标准模型的新物理理论的模型、机制和唯象学研究，探讨新物理的能量标度，并对作为热暗物质的中微子和新物理模型中可能作为温暗物质和冷暗物质的新型中微子的属性展开研究。 研究通过暗物质空间探测信号如宇宙线正负电子，反质子，弥散光子等限制和区分暗物质理论模型。系统研究暗物质属性对不同暗物质直接探测实验结果的影响。研究能够自恰解释当前暗物质探测实验结果与暗物质剩余丰度的暗物质模型及机制以及暗物质与重子物质起源的关联。

Understanding the nature of dark matter (DM) is the key issue of the current particle physics and cosmology. The proposal will focus on investigations of various DM models beyond the standard model, which is based on phenomenological study on DM indirect and direct detection experimental data. The indirect search signals such as cosmic-ray electron/positron, antiproton and diffuse gamma rays will be used to constrain and distinguish various DM models. The nature of neutrinos as hot, warm, and cold DM candidates related to new physics models will be investigated. The impact of the nature of DM in DM direct detection will be investigated systematically. Models or mechanisms lead to consistent explanation of the current experiments and the DM relic density, as well as the connections between the origins of DM and baryonic matter will be investigated.
