Description
Identifying the Nature of Dark Matter via Higgs portal.
There are three types of the models depending on the DM spin: scalar, fermion and vector DM models. In this talk, we consider renormalizable, unitary and gauge invariant Higgs portal DM models. For the Higgs portal singlet fermion and vector DM cases, the force mediator involves two scalar propagators, the SM-like Higgs boson and the dark Higgs boson. We will show that their interference generates interesting and important patterns in the mono-Zplus missing energy signatures at the ILC and LHC. In addition, we will further show that with VBF search strategies it will be possible to distinguish between Higgs portal DM from canonical wino DM scenarios at the LHC.
