Abstract
Measurements of the inclusive and differential fiducial cross sections for the Higgs boson production in the $\mathrm{H}\rightarrow{\rm Z}{\rm Z}\rightarrow4\ell$ ($\ell={\rm e},\mu$) decay channel are presented.The results are obtained from the analysis of proton-proton collision data recorded by the CMS experiment at the CERN LHC at a center-of-mass energy of $13~\mathrm{TeV}$, corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$.The measured inclusive fiducial cross section is $2.73\pm0.26~\mathrm{fb}$, in agreement with the standard model expectation of $2.86\pm0.15~\mathrm{fb}$.Differential cross sections are measured as a function of several kinematic observables sensitive to the Higgs boson production and decay to four leptons.A set of double-differential measurements is also performed, yielding a comprehensive characterization of the four leptons final state.Constraints on the Higgs boson trilinear coupling and on the bottom and charm quark coupling modifiers are derived from its transverse momentum distribution.All results are consistent with theoretical predictions from the standard model.
