Single top quark measurements with the CMS experiment

Single top quarks are produced at the Large Hadron Collider in electroweak processes via charged current interaction. This channel is very sensible to new physics signals, like anomalous couplings or flavour changing neutral current, due to the presence of an electroweak vertex. The latest results obtained with the data collected by the CMS experiment (CMS Collaboration, $JINST$, 3 (2008) S08004) in 2015–2018 at $\sqrt{s}$ = 13TeV at the Large Hadron Collider, studying both inclusive and differential cross sections, allow to precisely probe the structure of the interaction vertex and to search for deviations from the Standard Model predictions.
