| Abstract: A measurement of the associated production of a single top quark and a W boson in the final states with an electron or muon and jets using pp collisions with $\sqrt{s}= $ 13 TeV collected by the CMS detector at the CERN LHC is presented. The data used correspond to an integrated luminosity of 35.9 fb$^{-1}$. This result is the first observation of the tW process in the final states containing a muon or electron and jets, with an observed significance clearly exceeding 5 standard deviations. The measured signal strength is $\mu = $ 1.24 $\pm$ 0.18, consistent with unity. The inclusive cross section is determined to be 89 $\pm$ 4 (stat) $ \pm$ 12 (syst) pb. | ||
