Description

Measurements of single top­quark production in proton proton collisions are presented. The measurements include the first such measurements from the 13 TeV ATLAS dataset. In the leading order process, a W boson is exchanged in the t­channel. The single top­quark and anti­top total production cross sections, their ratio, as well as a measurement of the inclusive production cross section is presented. At 8 TeV, differential cross­section measurements of the t­channel process are also presented, these measurements include limits on anomalous contributions to the Wtb vertex. A measurement of the production cross section of a single top quark in association with a W boson, the second largest single­top production mode, is also presented. Finally, evidence for single­top production in the 8 TeV ATLAS dataset is presented. All measurements are compared to state­of­ the­art theoretical calculations.
