Single top quark production measurements in CMS

Single top quark can be produced via the electroweak interaction of the protons at the CMS experiment. There are 3 production mechanisms, known as t, tW and s channels. Studying the production of the single-top quark production in all these channels helps in better understanding of the electroweak interaction for heavy quarks. Recent results on the cross section measurements in proton-proton collisions by the CMS collaboration at center-of-mass energies of 7,8 and 13 TeV are reviewed in this report.
