The THDMa is a new physics model that extends the scalar sector of the Standard Model by an additional doublet as well as a pseudoscalar singlet and allows for mixing between all possible scalar states. In the gauge eigenbasis, the additional pseudoscalar serves as a portal to the dark sector, with a priori any dark matter spin states. The Inert Doublet model is another intriguing new physics model containing a dark matter candidate, which so far has not been investigated by the LHC experiments. I discuss current bounds as well as discovery prospects for both models at current and future colliders.
