Single-Top Quark Production at CMS

An overview of recent results of single-top quark production at the LHC using data collected with the CMS detector is presented. The CMS experiment has measured the electroweak production of the top quark in three production modes, namely t-channel, tW-channel, and s-channel. Measurements of the rare processes involving a single-top quark with a Z boson and a single-top quark with a $\gamma$ are also discussed. All measurements are in agreement with the standard model prediction, and no sign of physics beyond the standard model is observed.
