abstract
Measurements of the inclusive and differential fiducial cross sections for the Higgs boson production in the H $\to$ ZZ $\to$ 4$\ell$ ($\ell$ = 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 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. The measured inclusive fiducial cross section is 2.73 $\pm$ 0.26 fb, in agreement with the standard model expectation of 2.86 $\pm$ 0.1 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.

Off-shell Higgs boson measurements: Yukawa couplings, self-coupling, compositeness, and width
Using off-shell Higgs production in 138 fb^-1 of 13 TeV CMS data, the collaboration measured Γ_H = 5.1^{+2.0}_{-1.8} MeV, excluded no off-shell production at >5σ, and set the first direct 95% CL lower bound Λ_H > 870 ...

Search for Higgs boson production at high transverse momentum in the WW decay channel in proton-proton collisions at $\sqrt{s}$ = 13 TeV
A first dedicated search for highly Lorentz-boosted H->WW decays at the LHC finds mu = -0.19 +0.48/-0.46, consistent with no signal above background.

Measurements of Higgs boson production cross section in the four-lepton final state in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV
At sqrt(s)=13.6 TeV, the H->ZZ->4l fiducial production cross section is measured to be 2.89 +0.53/-0.49 (stat) +0.29/-0.21 (syst) fb, agreeing with the SM prediction 3.09 +0.27/-0.24 fb.
