Résumé :

Measurements of the inclusive and differential fiducial cross sections for theHiggs boson production in the H → ZZ → 4` (` = e, µ) decay channel are presented. Theresults are obtained from the analysis of proton-proton collision data recorded by the CMSexperiment at the CERN LHC at a center-of-mass energy of 13 TeV, corresponding to anintegrated luminosity of 138 fb−1. The measured inclusive fiducial cross section is 2.73 ±0.26 fb, in agreement with the standard model expectation of 2.86±0.1 fb. Differential crosssections are measured as a function of several kinematic observables sensitive to the Higgsboson production and decay to four leptons. A set of double-differential measurements isalso performed, yielding a comprehensive characterization of the four leptons final state.Constraints on the Higgs boson trilinear coupling and on the bottom and charm quarkcoupling modifiers are derived from its transverse momentum distribution. All results areconsistent with theoretical predictions from the standard model.
