CMS Detector Sensitivity to the Standard Model Higgs Boson in $\mathrm{H}\to\mathrm{ZZ^{(\ast)}}\to4{\rm leptons}$ Decay Channel

Presented are the results of the analysis of the CMS detector sensitivity to the Standard Model Higgs boson in its 4-lepton decay channel, $\mathrm{H}\to\mathrm{ZZ^{(\ast)}}\to4{\rm leptons}$, in the Higgs boson mass range from 115-600 GeV. The studies are based on the most recent full CMS detector simulation and mimic the real data analysis with the most critical calibrations extracted from ``data'' and all systematic uncertainties explicitly evaluated and taken into account.
