The current status of the searches for the SM Higgs boson in the H→ZZ(*)→4ℓ decay channel with the CMS experiment [1] is presented. The selection cuts for suppressing the backgrounds while keeping very high signal efficiencies are described, along with the data-driven algorithms implemented to estimate the background yields and the systematic uncertainties. With an integrated luminosity of 1.66 fb−1, upper limits at 95% CL on the SM-like Higgs cross section × branching ratio exclude cross sections from about one to two times the expected value from the Standard Model in the range 150 < mH < 420 GeV. No evidence for the existence of the SM Higgs boson has been found so far.
