DARK MATTER SEARCH AT LHC

The existence of significant amount of dark matter in the Universe is one of strongest motivations to expect new physics beyond the Standard Model. The observation of dark matter at the LHC is a grand challenge next to the discovery of the Higgs boson. Following sections present latest LHC results on the search for dark matter in various final states with large missing transverse energy using data collected in 2011 and 2012.
