Abstract 

   With the discovery of 125 GeV Higgs boson, all the Standard model (SM) particles have been found and it is naturally to ask what is the next new particle. The Dark Matter (DM) must be one of important tasks because it is already known with several astrophysical evidence. Still, It is not yet to exclude the probability of weak interaction massive particles (WIMPs), even though those evidence can be mainly explained by gravitational interaction between DM and SM particles. 

  In this talk, I will first review and summarize the current status of WIMP DM searches. After introduction of WIMP, I will present my previous works based on four different DM approaches: DM model test, DM direct detection, DM indirect detection, and DM production at the colliders. 

  Finally, I will propose what kind of interesting works can be done in the future. Such kind of future work might give us some hint whether is WIMP DM discovered potentially in future 20-30 years or not.
