Searches for direct stop production in the two lepton channel with the ATLAS experiment

Supersymmetric theories offer one of the most promising solutions to the Standard Model problems, addressing in particular the naturalness problem of the theory. Within this scenario the search of the top quark supersymmetric partner, called stop, plays a key role. The ATLAS Experiment has developed a dedicated strategy to search for this particle. The results obtained searching for stop pair production in two-lepton (electron and muon) final states using 20/fb of 8 TeV pp collisions data taken in 2012 are presented.
