Search for gluinos in events with two same-sign leptons, jets, and missing transverse momentum with the ATLAS detector in pp collisions at √s=7TeV

A search is presented for gluinos decaying via the supersymmetric partner of the top quark using events with two same-sign leptons, jets, and missing transverse momentum. The analysis is performed with 2.05fb - 1 of integrated luminosity from pp collisions at √s=7TeV collected by the ATLAS detector...
