Constraining Dark Matter using Mono-X, Dijet, and Dilepton Final States with the ATLAS Detector

Weakly-coupled TeV-scale particles may mediate interactions between dark matter (DM) and Standard Model (SM) particles. DM production at colliders may be evident in “mono-X” topologies, and mediator production in in dijet and dilepton events. The latest results obtained by the ATLAS experiment are presented and interpreted following the LHC DM WG guidelines, with particular focus on the complementarity between different collider searches as well as direct detection experiments.
