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 focuses on the dominant t-channel production process, assuming an integrated luminosity of 200 pb(-1) at a center-of-mass energy of 10TeV. An artificial neural network is employed to control background from tt 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.
