We combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson () in the process in collisions at the Fermilab Tevatron Collider at . With of integrated luminosity analyzed at CDF and at D0, the 95% confidence level upper limit on is 1.75 pb at , 0.38 pb at , and 0.83 pb at . 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.
