Measurement of Higgs boson properties in the four-lepton final state at $\sqrt s =$ 13 TeV at CMS

This paper reports the measurement of Higgs boson properties performed in the four-lepton final state using proton-proton collision data collected by the CMS experiment at CERN in 2016 at a centre-of-mass energy of 13TeV. In particular, the measurement of the signal strength modifier (defined as the ratio of the observed Higgs boson rate in the four-lepton decay channel to the Standard Model expectation) is presented both inclusively and separately for the individual Higgs boson production modes. The measurements of the Higgs boson mass and width are also reported.
