Single top-quarks at the LHC

This article summarises the status of measurements of single top-quark production in all channels at the LHC for a centre-of-mass energy of 7 TeV with the full 2011 data set and for a centre-of-mass of 8 TeV for the t-channel cross-section. Results are reported from the ATLAS and CMS experiments. Both experiments also report evidence for the W t-channel production which has never been observed before. ATLAS also sets a limit on the s-channel cross-section. So far, the measured cross sections are in good agreement with the predictions by the Standard Model.
