Abstract

We combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson (H) in the process ggHW+W in pp¯ collisions at the Fermilab Tevatron Collider at s=1.96TeV. With 4.8fb1 of integrated luminosity analyzed at CDF and 5.4fb1 at D0, the 95% confidence level upper limit on σ(ggH)×B(HW+W) is 1.75 pb at mH=120GeV, 0.38 pb at mH=165GeV, and 0.83 pb at mH=200GeV. Assuming the presence of a fourth sequential generation of fermions with large masses, we exclude at the 95% confidence level a standard-model-like Higgs boson with a mass between 131 and 204 GeV.
