Description
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 36 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 μ = 1.24 ± 0.18, consistent with unity. The inclusive cross section is determined to be 89 ± 4 (stat) ± 12 (syst) pb.
