摘要：

We consider the supersymmetric extension of the standard model with an additional singlet S, the non-minimal supersymmetric standard model (NMSSM), in the limit tan beta similar or equal to m(t)/m(b). We embed this model in a supergravity framework with universal boundary conditions and analyze the renormalization group improved tree-level potential. We examine the relationship between this model and the minimial supersymmetric standard model (MSSM), and discuss the novel connections between the two when tan beta is large. Strong correlations between the free parameters of the nonminimal model are found and the reasons for these discussed. The singlet vacuum expectation value is forced to be large, of the order of 10 TeV. The radiatively corrected mass of the lightest Higgs boson is found to be less than or similar to 140 GeV.
