Measurements of Higgs boson properties from on-shell and off-shell production in the four-lepton final state

September 2018

Abstract: Studies of on-shell and off-shell Higgs boson production in the four-lepton final state are presented, using data from the CMS experiment at the LHC that corresponds to an integrated luminosity of 80.2 fb$^{-1}$ at 13 TeV. Joint constraints are set on the width of the Higgs and parameters that express its anomalous couplings to two electroweak vector bosons using both on-shell and off-shell production of the Higgs boson. These results are combined with results from the data collected at center-of-mass energies of 7 and 8 TeV, corresponding to integrated luminosities of 5.1 and 19.7 fb$^{-1}$, respectively. Matrix element techniques, which combine kinematic information from the decay particles and the associated jets, are used to identify the production mechanism and to increase sensitivity to the Higgs boson signal and its anomalous couplings. The observations are consistent with expectations for a Standard Model Higgs boson. This document has been revised with respect to the version dated September 17, 2018.
