Searches for direct supersymmetric gaugino and slepton pair production in final states with leptons with the ATLAS detector

A search for direct production of supersymmetric gauginos and sleptons in final states with two and three leptons is presented. The two lepton analysis uses 4.7 fb$^{-1}$ of proton-proton collision data at $\sqrt{s} = 7$ TeV, while the three lepton analysis uses 13 fb$^{-1}$ at $\sqrt{s} = 8$ TeV. All data was recorded by the ATLAS detector at the Large Hadron Collider. The results are interpreted in the phenomenological minimal supersymmetric Standard Model, as well as simplified models. No significant excess above the Standard Model expectation is observed. Limits on the particle masses are placed at the 95% confidence level. In simplified models, chargino masses are excluded up to 580 GeV in the presence of light sleptons and up to 300 GeV in case of heavy sleptons.
