Measurement of the production cross section for single top quarks in association with W bosons in proton-proton collisions at $$ \sqrt{s}=13 $$ TeV
Here, a measurement is presented of the associated production of a single top quark and a W boson in proton-proton collisions at $$\sqrt{s}=$$ 13 TeV by the CMS Collaboration at the CERN LHC. The data collected corresponds to an integrated luminosity of 35.9 fb$$^{-1}$$. The measurement is performed using events with one electron and one muon in the final state along with at least one jet originated from a bottom quark. A multivariate discriminant, exploiting the kinematic properties of the events, is used to separate the signal from the dominant $$\mathrm{t\overline{t}}$$ background. The measured cross section of 63.1 $$\pm$$ 1.8 (stat) $$\pm$$ 6.4 (syst) $$\pm$$ 2.1 (lumi) pb is in agreement with the standard model expectation.
