Abstract:

Majorana Dark matter (DM) model can be classified by their electroweak charge. In this talk I will start with singlet DM effective theory (EFT) and then move to singlet-doublet mixed case. In singlet case, we will present a global picture by taking all the operators and DM constraints into account. However, the EFT is no longer valid with current LHC 8 TeV region. Therefore, by the help from UV models, this problem can be fixed non-trivially. The current monojet and dijet constraint power will be presented. Moreover, a future prospect on the future DM direct detections and e+e- colliders (CEPC and ILC) will be also demonstrated. In the second part of talk, I will show some of our preliminary result on singlet-doublet mixed DM model by using the similar manner.
