Searches for electroweak production of supersymmetric gauginos and sleptons with the ATLAS detecto

This document presents results from the searches for electroweak production of gauginos or sleptons decaying into leptonic final states with missing transverse momentum performed using 20.3 fb$^{-1}$ of proton-proton collision data at $\sqrt{s} = 8$ TeV recorded with the ATLAS experiment at the Large Hadron Collider. No significant excesses are observed with respect to the prediction from Standard Model processes. Limits are set on a wide range of SUSY models.
