Resumen:
Results are presented of searches for the production of supersymmetric
particles decaying into final states with missing transverse momentum
and exactly two isolated leptons in sqrt{s}=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 significant excesses are
observed. Based on specific benchmark 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.
