| Abstract: Combined measurements of Higgs boson production and decay rates are presented. The analyses included use proton-proton collision data recorded by the CMS experiment at $ \sqrt{s}= $ 13 TeV from 2016 to 2018, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. The statistical combination is based on analyses which measure the following decay channels: $ \mathrm{H}\rightarrow\gamma\gamma $, $ \mathrm{H}\rightarrow\mathrm{ZZ} $, $ \mathrm{H}\rightarrow\mathrm{WW} $, $ \mathrm{H}\rightarrow\tau\tau $, $ \mathrm{H}\rightarrow\mathrm{bb} $, $ \mathrm{H}\rightarrow\mu\mu $ and $ \mathrm{H}\rightarrow\mathrm{Z}\gamma $. Each decay channel targets multiple Higgs boson production modes. Searches for invisible Higgs boson decays are also considered, as well as an analysis which measures offshell Higgs boson production in the $ \mathrm{H} \rightarrow \mathrm{ZZ} \rightarrow 4\ell $ decay channel. The best-fit inclusive signal yield is measured to be 1.014 $ ^{+0.055}_{-0.053} $ times the standard model expectation, for a Higgs boson mass of 125.38 GeV. Additional results are provided for various assumptions on Higgs boson production and decay. This includes measurements of production mode cross sections and branching fractions, measurements of kinematic regions defined by the simplified template cross section framework, as well as interpretations in the coupling modifier and standard model effective field theory frameworks. This note represents the most comprehensive study of Higgs boson production and decay performed by the CMS experiment to-date. | ||
