We present the results of direct searches for the Standard Model Higgs boson at the Tevatron. Results are derived from the complete Tevatron Run II dataset, with a measured integrated luminosity of 10 fb-1 of proton–antiproton data. The searches are performed for assumed Higgs masses between 90 and 200 GeV /c2. We observe an excess of events in the data compared with the background predictions, which is most significant in the mass range between 115 and 135 GeV /c2, consistent with the Higgs-like particle recently observed by ATLAS and CMS. The largest local significance is 2.7 standard deviations, corresponding to a global significance of 2.2 standard deviations. We also combine separate searches for [Formula: see text] and H→W+W-, and find that the excess is concentrated in the [Formula: see text] channel, although the results in the H→W+W- channel are still consistent with the possible presence of a low-mass Higgs boson.
