The combination is presented of searches for a standard model (SM) Higgs boson in eight decay modes: H → γγ, H → ττ, H → bb, H → WW* → 2ℓ2v, H → ZZ* → 4ℓ, H → ZZ → 2ℓ2τ, H → ZZ → 2ℓ2v, and H → ZZ → 2ℓ2q. The searches were performed by the CMS Collaboration using 1.1-1.7 fb−1 of integrated luminosity, depending on the analysis. No excess compatible with a SM Higgs signal has been observed; the largest excursion of the observed data from the expected background has a probability of 0.4 after taking into account the look-elsewhere effect. The SM Higgs boson is excluded at 95% C.L. in three mass ranges 145-216, 226-288, and 310-400 GeV/c2, while the expected exclusion range is 130-440 GeV/c2.
