ATLAS Search Strategy for Single-Top Production

The search strategy of the ATLAS experiment for single top quark production during the first two years of data-taking at the LHC is presented. The study fucuses on the dominant t-channel production process, assuming an integrated luminoisyt of 200/pb at a center-of-mass energy of 10 TeV. An artificial neural network is employed to control background from ttbar production and W boson production in association with jets. Single-top sensitivities obtained with a sequential cut analysis and a robust likelihood ratio discriminant are compared.
