  报告简介:

  I will be talking about Dark Matter (WIMPs) and its direct detection.

  Dark Matter (DM) is one of the most critical questions to be understood and answered in fundamental physics. Among other DM candidates, Weakly Interactive Massive Particles (WIMPs) is the most discussed one. WIMPs' direct detection is the research of multi-disciplines that wraps astrophysics, particle physics, and nuclear physics together. It can explore the untouching region of the interaction between WIMPs and nucleons in a way other methods like indirect detection and the searches on colliders can not reach.

  I will firstly review the search of DM (WIMPs): the evidence of its existence from astrophysics and cosmology, the strategy of WIMPs detection, the current status of various experiments of WIMPs' direct detection.

  Secondly, I will address two WIMPs direct experiments in detail: DArk Matter In CCDs (DAMIC) and LUX-ZEPLIN (LZ), which hunt for low-mass (~ 1 - 10 GeV/c^2) and high-mass (~ 10 - 1000 GeV/c^2) WIMPs, respectively. 

  In the end, I will be talking about a brand new and very competitive experiment for low-mass (~ 100s MeV/c^2 - 10 GeV/c^2) WIMPs hunting: A Liquid hElium Time projection cHambEr In dArk matter (ALETHEIA).
