Supersymmetric Higgs Bosons at the Limit
T. Elliott, S. F. King, P. L. White
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 mh< 145 GeV for mt=90 GeV, decreasing to mh< 123 GeV for mt=180 GeV. We also discuss the light Higgs spectrum in the region of parameter space close to the upper bound.
