Searches for dark matter at ATLAS and CMS

Cosmological and astrophysical observations indicate the presence of Dark Matter in the universe which cannot be explained by the Standard Model. Searches for Dark Matter are performed by both the ATLAS and CMS experiment at the LHC in events involving large missing transverse momentum in the final state. So far no signal for physics beyond the Standard Model has been found. An overview of the most recent results by both the ATLAS and CMS collaboration based on the full proton-proton collision dataset collected at a centreof-mass energy of 13 TeV in 2015 and 2016 is presented.
