Search for a heavy top-quark partner in final states with two leptons with the ATLAS detector at the LHC

Abstract (data abstract)
CERN-LHC. Search for direct pair production of heavy top-quark partners in proton-proton interactions of centre-of-mass energy of 7 TeV with a final state containing 2 leptons. The data sample taken during 2011 has a total integrated luminosity of 4.7 fb-1. Two models are compared with the data, one with a spin 1/.2 heavy top-quark and a heavy neutral partner and the other a supersymmetric scalar top quark and a massless neutralino. See the text of the paper for more details.
