Description
In the minimal supersymmetric standard model (MSSM), when radiative corrections are included, the mass of the CP=+1 lightest Higgs boson is bounded by ∼110 GeV for mt<150 GeV and a scale of supersymmetry breaking ∼1 TeV. In non-minimal supersymmetric standard models (NMSSM) upper bounds on the mass of the corresponding scalar Higgs boson arise if the theory is required to remain perturbative up to scales much-gt G-1/2F. We have computed those bounds for two illustrative NMSSM: (i) A model with an arbitrary number of gauge singlets; (ii) A model with three SU(2)L triplets with Y=0, ±1. We have integrated numerically the corresponding renormalization group equations (RGE), including the top and bottom quark Yukawa couplings, and added one-loop radiative corrections. For mt>91 GeV the absolute bounds are ∼140 GeV for both models
