Single-Top Quark Production Measurements Using the ATLAS Detector

Measurements of single top-quark production in proton-proton collisions are presented at a centre-of-mass energy of 8$\,$TeV and 13$\,$TeV. A measurement of the cross-section where a W boson is exchanged in the $t$-channel is discussed and the results for the inclusive production cross-section are presented. A measurement of the production cross-section of a single top quark in association with a W boson, the second largest single-top production mode, is also presented. Evidence for single-top production in the $s$-channel with the 8$\,$TeV ATLAS dataset is discussed. Finally, measurements of the properties of the Wtb vertex allows to set limits on anomalous couplings. All measurements are compared to state-of-the-art theoretical calculations.
