Studies of Single-top Production in ATLAS

We report results from studies of the production of single-top quark events using 2011 data from the ATLAS detector collected from proton-proton collisions occurring at 7 TeV center-of-mass energy. Single-top quark production is an electroweak process and is expected to be sensitive to new physics that can modify the Wtb coupling. We examine the standard model production mechanisms by isolating signal events while separating background events based on the kinematic signatures of the single-top quark processes. We present a measurement of the t-channel production cross-section and limits on the s-channel and Wt associated production cross-sections.
