description This poster presents the estimation of non-prompt and fake lepton backgrounds developed in the context of ATLAS top analyses performed with the 8 TeV dataset. Two different data- driven methods are described and results are compared. The first method is based on the measurements of efficiencies of leptons with relaxed identification criteria. The second one is based on the construction of templates for non-prompt and fake leptons.
