Description
Properties of the Higgs boson are measured in the H → ZZ →
4ℓ (ℓ = e, μ) decay channel. A data sample of proton-proton
collisions at √{s}=13 TeV, collected with the CMS detector at the
LHC and corresponding to an integrated luminosity of 35.9
fb-1 is used. The signal strength modifier μ, defined as
the ratio of the observed Higgs boson rate in the H → ZZ →
4ℓ decay channel to the standard model expectation, is measured to
be μ = 1.05 - 0.17 + 0.19 at m H =
125.09 GeV, the combined ATLAS and CMS measurement of the Higgs boson
mass. The signal strength modifiers for the individual Higgs boson
production modes are also measured. The cross section in the fiducial
phase space defined by the requirements on lepton kinematics and event
topology is measured to be 2. 92 - 0.44 + 0.48
(stat) - 0.24 + 0.28 (syst)fb, which is compatible
with the standard model prediction of 2.76 ± 0.14 fb.
Differential cross sections are reported as a function of the transverse
momentum of the Higgs boson, the number of associated jets, and the
transverse momentum of the leading associated jet. The Higgs boson mass
is measured to be m H = 125.26 ± 0.21 GeV and the
width is constrained using the on-shell invariant mass distribution to
be ΓH< 1.10 GeV, at 95% confidence level. [Figure
