Supersymmetric Higgs Bosons at the Limit

Abstract

We obtain an improved upper bound on the lightest neutral CP-even Higgs boson mass from a low energy renormalisation-group analysis of the Higgs sector of the next-to-minimal supersymmetric standard model. We find $m_h<145$ 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 region of parameter space close to the upper bound.
