Description
Integrated fiducial cross sections for the production of four leptons
via the H → 4 ℓ decays ( ℓ = e, μ) are measured in pp
collisions at √{s}=7 and 8TeV. Measurements are performed with data
corresponding to integrated luminosities of 5.1 fb-1 at 7TeV,
and 19.7 fb-1 at 8 TeV, collected with the CMS experiment at
the LHC. Differential cross sections are measured using the 8 TeV data,
and are determined as functions of the transverse momentum and rapidity
of the four-lepton system, accompanying jet multiplicity, transverse
momentum of the leading jet, and difference in rapidity between the
Higgs boson candidate and the leading jet. A measurement of the Z →
4 ℓ cross section, and its ratio to the H → 4 ℓ cross
section is also performed. All cross sections are measured within a
fiducial phase space defined by the requirements on lepton kinematics
and event topology. The integrated H → 4 ℓ fiducial cross
section is measured to be 0. 56 - 0.44 + 0.67
(stat) - 0.06 + 0.21 (syst) fb at 7 TeV, and 1. 11
- 0.35 + 0.41 (stat) - 0.10 +
0.14 (syst) fb at 8 TeV. The measurements are found to be
compatible with theoretical calculations based on the standard model.
