Abstract

The two-loop Higgs mass upper bounds are reanalyzed. Previous results for a cutoff scale Λ≈ few TeV are found to be too stringent. For Λ=1019 GeV we find MH < 180 4 5 GeV, the first error indicating the theoretical uncertainty, the second error reflecting the experimental uncertainty due to mt = 175 6 GeV. We also summarize the lower bounds on MH. We find that a SM Higgs mass in the range of 160 to 170 GeV will certainly allow for a perturbative and well-behaved SM up to the Planck-mass scale ΛPl 1019 GeV, with no need for new physics to set in below this scale.
