Dark matter searches at LHC

Besides Standard Model measurements and other beyond-SM studies, the ATLAS and CMS experiments at the LHC will search for Supersymmetry (SUSY), one of the most attractive explanation for Dark Matter. The SUSY discovery potential with early data will be presented together with recent results acquired with 2010 data. Emphasis will be placed on the interpretation of a possible positive SUSY signal as an explanation of Dark Matter.
