Abstract
We combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson (H) in the process gg-->H-->W+W- in pp̅ collisions at the Fermilab Tevatron Collider at [sqrt]s=1.96 TeV. With 4.8 fb-1 of integrated luminosity analyzed at CDF and 5.4 fb[superscript -1] at D0, the 95% confidence level upper limit on σ(gg-->H)×B(H-->W+W-) is 1.75 pb at mH=120 GeV, 0.38 pb at m[subscritp H]=165 GeV, and 0.83 pb at m[subscritp H]=200 GeV. 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.
