Search with the ATLAS detector for new physics with significant missing transverse energy and two isolated leptons

We present results for searches of new physics in the context of supersymmetry, with a signature of significant missing transverse energy and two isolated leptons with the experiment ATLAS at the LHC. Three analyses are presented, the first two are inclusive analyses with leptons of opposite charge and same charge respectively. The third one is an exclusive analysis that searches for excess of same flavour and opposite charge leptons. A dataset of 1 $fb^{-1}$ is used and model independent limits are presented. This is an update of a previous analysis done with roughly 30 times less luminosity.
