Measurement of differential and integrated fiducial cross sections for Higgs boson production in the four-lepton decay channel in pp collisions at s√=7s=7 and 8 TeV

AbstractIntegrated fiducial cross sections for the production of four leptons via the H → 4ℓ decays (ℓ = e, μ) are measured in pp collisions at s√=7s=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 → 4ℓ cross section, and its ratio to the H → 4ℓ 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 → 4ℓ 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.
