abstract: The production of top quarks is abundant at the Large Hadron Collider (LHC) and the measurement of single top quarks can provide access to interesting properties of the electroweak interaction at the tWb vertex or the polarisation of the top quark. Deviations from Standard Model predictions would give hints to new physics. While at the previous hadron collider, Tevatron, only evidence for the t- and s-channel production was found, the LHC can also provide access to the single top production channel with an associated real W boson. This talk summarises the progress on single-top quark measurements from the ATLAS and CMS collaborations at the LHC.
