Searches for the electroweak production of slepton pairs and chargino pairs decaying into final states with two leptons and missing transverse momentum ar e performed using 20.7 fb−1 of proton-proton collision data at √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 the masses of the lightest chargino for different lightest neutralino mass hypotheses withi nthe framework of the phenomenological minimal super symmetric Standard Model and of the simplified models.
