摘要：

We investigate the dark matter constraints for the nonminimal SUSY standard model (NMSSM). The cosmologically restricted mass spectra of the NMSSM are compared to the minimal SUSY standard model (MSSM). The differences of the two models concerning the neutralino, sfermion and Higgs sector are discussed. The dark matter condition leads to cosmologically allowed mass ranges for the SUSY particles in the NMSSM: m(sic) < 300 GeV, m(sic) < 300 GeV, 300 GeV < m(sic) < 1900 GeV, 200 GeV < m(sic) < 1500 GeV, 350 GeV < m((g) over tilde) < 2100 GeV and for the mass of the lightest scalar Higgs m(sic) < 140 GeV.
