Combined measurements of the production and decay rates of the Higgs boson, as well as its couplings to vector bosons and fermions, are presented. The analysis uses the LHC proton-proton collision data set recorded with the CMS detector in 2016 at s√=13TeVs=13TeV, corresponding to an integrated luminosity of 35.9fb−1fb−1. The combination is based on analyses targeting the five main Higgs boson production mechanisms (gluon fusion, vector boson fusion, and associated production with a WW or ZZ boson, or a top quark-antiquark pair) and the following decay modes: H→γγH→γγ, ZZZZ, WWWW, ττττ, bbbb, and μμμμ. Searches for invisible Higgs boson decays are also considered. The best-fit ratio of the signal yield to the standard model expectation is measured to be μ=1.17±0.10μ=1.17±0.10, assuming a Higgs boson mass of 125.09GeV125.09GeV.
