Abstract
We obtain an improved upper bound on the lightest neutral CP-even Higg s boson mass from a low energy renormalisation-group analysis of the H iggs sector of the next-to-minimal supersymmetric standard model. We f ind m(h) < 145 GeV for m(t) = 90 GeV, decreasing to m(h) < 123 GeV for m(t) = 180 GeV. We also discuss the light Higgs spectrum in the regio n of parameter space close to the upper bound.
