The theory uncertainty for the Higgs-mass prediction is dominated by DSWW. Extrema in Higgs mass from ZFITTER: t_mass h_mass limit Maximal h_mass DSWW=-1 173.28 96.9 160.5 Default setting 173.27 92.0 153.4 Minimal h_mass DSWW=+1 173.26 87.2 146.5 The blue band will be the area enclosed by the two ZFITTER DSWW=+-1 \Delta\chi^2 curves. The one-sided 95%CL (90% two-sided) upper limit on MH is given by ZFITTER's DSWW=-1 curve: MH <= 161 GeV (one-sided 95%CL incl. TU) ----------------------------------------- (increasing to 185 GeV when including the LEP-2 direct search limit). EOF
