Complementarities and future of dark matter searches

Dark Matter can be sought in complementary experiments: direct detection, indirect detection and colliders all contribute to a comprehensive set of searches for weakly interacting massive particles (WIMPs). This talk underlines the searches for Dark Matter by the ATLAS (and CMS) experiments in the context of this complementarity, highlighting recent work by the two collaborations on the benchmark models chosen. Specifically, the use of models that include a mediator particle between SM and DM as opposed to effective field theories may allow collider experiments to further their impact in the global picture of Dark Matter searches. In addition the potential for Dark Matter searches in Run2 at LHC will be reviewed.
