| Summary: | 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 = 13 TeV, corresponding to
an integrated luminosity of 35.9 fb−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 W or Z boson, or a top quarkantiquark pair) and the following decay modes: H → γ γ ,
ZZ, WW, τ τ , bb, and μμ. 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 ± 0.10, assuming a Higgs boson mass of
125.09 GeV. Additional results are given for various assumptions on the scaling behavior of the production and decay
modes, including generic parametrizations based on ratios
of cross sections and branching fractions or couplings. The
results are compatible with the standard model predictions in
all parametrizations considered. In addition, constraints are
placed on various two Higgs doublet models. |
