| Abstract: Measurements of the inclusive and differential fiducial cross sections for Higgs boson production in pp collisions at center-of-mass energies of $\sqrt{s}= $ 7 TeV and 8 TeV using $ \mathrm{H} \rightarrow 4\ell$ decays ($\ell = e, \mu$) are presented. Measurements are based on 5.1 fb$^{-1}$ (19.7 fb$^{-1}$) of 7 (8) TeV proton-proton collision data, recorded with the CMS detector at the LHC. The measurements of differential cross section are performed in bins of the transverse momentum and rapidity of the four-lepton system, jet multiplicity, transverse momentum of the leading jet, and distance in rapidity between the Higgs boson candidate and the leading jet. A measurement of the cross section of Z boson production in the $\mathrm{Z} \rightarrow 4\ell$ decay channel and its ratio to the Higgs boson production cross section in the $\mathrm{H} \rightarrow 4\ell$ channel is also performed. The inclusive fiducial cross section for Higgs boson production in the $\mathrm{H}\rightarrow 4\ell$ decay channel is measured to be 0.56$^{+0.67}_{\rm -0.44}$ (stat) $^{+0.21}_{-0.06}$ (syst) fb for proton-proton collisions at 7 TeV and 1.11$^{+0.41}_{-0.35}$ (stat) $^{+0.14}_{-0.10}$ (syst) fb for proton-proton collisions at 8 TeV. The results of all measurements are compared with theoretical calculations based on the Standard Model and no significant deviation is observed. | ||
