We investigate possibilities of search for the Standard Model Higgs boson in the H® ZZ ® 4l^± channel in the upper mass reach in the Compact Muon Solenoid detector (CMS). By using appropriate cuts on the data, it was found that CMS can detect Higgs boson up to the mass of about 750 GeV at ł 5 s significance level with the designed integrated luminosity of 10⁵ pb^-1. The mass reach extends to about 850 GeV at 3·10⁵ pb^-1.
