Abstract
A measurement of the cross section of the associated production of a single
top quark and a W boson in final states with a muon or electron and jets in proton-proton
collisions at √
s = 13 TeV is presented. The data correspond to an integrated luminosity of
36 fb−1
collected with the CMS detector at the CERN LHC in 2016. A boosted decision tree
is used to separate the tW signal from the dominant t¯t background, whilst the subleading
W+jets and multijet backgrounds are constrained using data-based estimates. This result
is the first observation of the tW process in final states containing a muon or electron and
jets, with a significance exceeding 5 standard deviations. The cross section is determined
to be 89 ± 4 (stat) ± 12 (syst) pb, consistent with the standard model.
