Resumen:
Results are presented of searches for the production of supersymmetric particles decaying into nal states with missing transverse momentum and exactly two isolated leptons in 7 TeV proton- proton collisions at the Large Hadron Collider. Search strategies requiring lepton pairs with identical sign or opposite sign electric charges are described. In a data sample corresponding to an integrated luminosity of 35 pb-1 collected with the ATLAS detector, no signi cant excesses are observed. Based on speci c bench- mark models, limits are placed on the squark mass between 450 and 690 GeV for squarks approximately degenerate in mass with gluinos, depending on the supersymmetric mass hierarchy considered.
