Searches for direct stop production in events with two leptons in √s = 8 TeV pp collisions using 20 fb−1 of ATLAS data

Abstract

Three searches for direct top squark pair production are presented. They target different decay modes, each with two leptons (electrons or muons) in the final state. The searches use 20.3 fb−1of pp collision data at √s = 8 TeV collected by the ATLAS experiment at the Large Hadron Collider. No excesses over Standard Model expectations are observed, 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.
