Abstract

We quantify the extent to which naturalness is lost as experimental lower bounds on the Higgs boson mass increase, and we compute the natural upper bound on the lightest supersymmetric Higgs boson mass. We find that it would be unnatural for the mass of the lightest supersymmetric Higgs boson to saturate its maximal upper bound. In the absence of significant fine-tuning, the lightest Higgs boson mass should lie below 120 GeV, and in the most natural cases it should be lighter than 108 GeV. For modest tanβ, these bounds are significantly lower. Our results imply that a failure to observe a light Higgs boson in experiments previous to the CERN LHC becoming operational could provide a serious challenge to the principal motivation for weak-scale supersymmetry.
