摘要：

We present a detailed analysis of the particle spectrum of the non-minimal supersymmetric standard model (NMSSM), containing two Higgs doublets and a singlet, in the limit tan beta similar or equal to m(t)/m(b). This is compared with the corresponding particle spectrum of the minimal supersymmetric standard model (MSSM). In this limit the singlet vacuum expectation value is forced to be large, of the order of 10 TeV, and the singlet decouples from the lightest scalar Higgs boson and the neutralinos. With the exception of the lightest Higgs boson, the particle spectrum in the model turns out to be heavy. The radiatively corrected lightest Higgs boson mass is in the neighbourhood of similar to 130 GeV.
