Measurements of the production of the standard model Higgs boson decaying to a Wboson pair are reported. The W+W−candidates are selected in events with an oppositely charged lepton pair, large missing transverse momentum, and various numbers of jets. To select Higgs bosons produced via vector boson fusion and associated production with a Wor Zboson, events with two jets or three or four leptons are also selected. The event sample corresponds to an integrated luminosity of 35.9fb−1, collected in ppcollisions at √s=13TeVby the CMS detector at the LHC during 2016. Combining all channels, the observed cross section times branching fraction is 1.28+0.18−0.17times the standard model prediction for the Higgs boson with a mass of 125.09GeV. This is the first observation of the Higgs boson decay to Wboson pairs by the CMS experiment.
