Search for supersymmetric particles in events with lepton pairs and large missing transverse momentum in $\sqrt{s}=7~\mbox{TeV}$ proton–proton collisions with the ATLAS experiment

Results are presented of searches for the produc- tion of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons in √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 de- scribed. In a data sample corresponding to an integrated lu- minosity of 35 pb−1 collected with the ATLAS detector, no significant excesses are observed. Based on specific 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.
