Abstract

The inclusive cross-section for tW production in proton-proton collisions at √(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 tt background through the use of multivariate discriminants designed to separate the two processes. The measured cross-section of σ= 63.1 ± 1.8~(\rm stat) ± 6.0~(\rm syst) ± 2.1~(\rm lumi) pb is in agreement with standard model expectations.
