Description
We propose a hybrid framework in the form of an effective theory, including both the dark matter states and a mediator connecting the former to the Standard Model fields. The framework overcomes the problems of traditional DM-EFT regarding the validity at high energies at collider experiments and improves the generality of the simplified models.
For fermionic and scalar dark matter with a (pseudo-)scalar mediator, the leading effects originate from dimension-five operators, allowing to capture them with a rather small set of new couplings.
The correlations between constraints from reproducing the correct relic density, direct-detection experiments, and mono-jet and Higgs + missing energy signatures at the LHC are analysed.
