Combined measurements of Higgs boson production and decay rates are presented, representing the most comprehensive study of Higgs boson production and decay performed by the CMS experiment to date. The included analyses use proton-proton collision data recorded by the CMS experiment at √s = 13 TeV from 2016 to 2018, corresponding to an integrated luminosity of 138 fb−1. The statistical combination is based on analyses that measure the following decay channels: H → γγ, H → ZZ, H → WW, H → ττ, H → bb, H → μμ, and H → Zγ → ``γ (where ` = e, μ). Measurements in kinematic regions defined by the simplified template cross section framework are also provided, as well as interpretations in the coupling modifier and standard model effective field theory frameworks. The coupling modifier interpretation is further used to place constraints on various two-Higgs-doublet models. The results show good compatibility with the standard model predictions for the majority of the measured parameters.
