Upper limits on the heavy neutral Higgs boson production cross section times its branchingratio tob ̄bare set, ranging from 4.0 to 0.6 pb at 95% confidence level over a Higgs boson mass range of450 to 1400 GeV. Results are interpreted within the two-Higgs-doublet model and the minimalsupersymmetric Standard Model.
