Description
Summary:The inclusive cross-section for tW production in proton-proton collisions at \(\sqrt{s} = 13\) TeV is measured with a dataset corresponding to an integrated luminosity of 35.9 fb\(^{-1}\) collected by the CMS experiment. The measurement is performed in events with one electron and one muon, and exploits kinematic differences between the signal and the dominating \(t\bar{t}\) background through the use of multivariate discriminants designed to separate the two processes. The measured cross-section of \(\sigma = 63.1 \pm 1.8~({\rm stat}) \pm 6.0~({\rm syst}) \pm 2.1~({\rm lumi})\) pb is in agreement with standard model expectations.
