Abstract

The inclusive cross-section for tW production in proton-proton collisions at s=13\sqrt{s} = 13 TeV is measured with a dataset corresponding to an integrated luminosity of 35.9 fb1^{-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 ttˉt\bar{t} background through the use of multivariate discriminants designed to separate the two processes. The measured cross-section of σ=63.1±1.8 (stat)±6.0 (syst)±2.1 (lumi)\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.
