ATLAS Highlights on DM Searches in Exotic Models

Dark matter could be produced at the LHC if it interacts weakly with the Standard Model. The search for dark matter can be performed directly, by looking for a signature of large missing transverse momentum coming from the dark matter candidates escaping the detector, measured against an accompanying visible object (jet, photon, vector boson). It can also be performed indirectly, by looking for the intermediate mediators which would couple the dark matter particles to the Standard Model. The mediator could indeed decay to jets or leptons, leading to a resonant signature which can be probed. A broad and systematic search program covering these various possibilities with the ATLAS detector is in place: the talk will review the latest results of these searches, excluding the searches involving a Higgs boson which will be covered in a dedicated talk.
