Abstract

Measurements of the single top quark production cross-sections in proton collisions with the ATLAS detector at the Large Hadron Collider are presented. The single top-quark production in the t and Wt-channels and the determination of the CKM matrix element |Vtb| are discussed. A separate measurement of the top and antitop quark cross-sections and their ratio is shown. These measurements are sensitive to the parton distribution function in the proton. In addition, limits on exotic production in single top quark processes are outlined. This also includes the search for flavour-changing neutral currents and for additional W’ bosons in the s-channel.
