Upper limits to fermion masses in the Glashow-Weinberg-Salam model
Journal Article

· Phys. Rev. D; (United States)
Upper limits on the mass m/sub f/ of a fermion in the Glashow-Weinberg-Salam model were previously found by requiring that our vacuum be an absolute minimum of the one-loop Higgs potential; for a Higgs-boson mass m/sub H/< or approx. =150 GeV, it was found that m/sub f/< or approx. =100 GeV. We note that including the effect of running couplings in the one-loop term enlarges the range of allowed masses based on this constraint. Requiring only that the universe arrive in our vacuum and stay there for over 10/sup 10/ yr further increases this bound to m/sub f/< or approx. =200 GeV.
