Single Top quark production cross section measurements using the ATLAS detector

Single top-quark production cross section measurements in proton-proton collisions are presented based on the 8 TeV and 13 TeV data collected by ATLAS detector . For the production of single top-quarks and single anti-top-quarks through t-channel, the fiducial and total production cross sections, their ratio, as well as measurements of inclusive and differential cross-sections are presented. Measurements of the inclusive and differential production cross section of a single top quark in association with a W boson, the second largest single-top production mode, are also presented. Rare single top quark measurement in the t-channel in association with with Z boson is also presented.
