Description
We will discuss some simple, but rather general scenarios, in which a (fermionic) dark matter interacts with Standard Model fermions through a mediator whose mass is accessible to collider production. Focussing in particular on Z/Z' mediators, we will show how the constraints from Dark Matter phenomenology, in particular the correct relic abundace and the limits from Direct Detection, determine the nature, axial or vectorial, of the dark matter couplings to these states. Particularly interesting is the case of a Z-portal scenario, which can be entirely probed, up to DM masses of 2 TeV by next future detectors. We will then show how these constraints affect searches of New Physics at LHC as well as prospects of dark matter detection at a Linear Collider.
