Searches for direct stop production in events with two leptons in sqrt(s) = 8 TeV pp collisions using 20 fb-1 of ATLAS data

Three searches for direct top squark pair production, targeting di erent decay modes yielding two leptons (electrons or muons) in the final state, are presented. Each search uses 20.3 fb-1 of pp collision data at sqrt(s) = 8 TeV collected by the ATLAS experiment at the Large Hadron Collider. No excesses over Standard Model expectations are found, and the results are interpreted under the separate assumptions that the light top squark decays to a b-quark and the lightest chargino, or to a t-quark and the lightest neutralino.
