摘要：

We estimate the top quark, lightest sparticle (LSP), and Higgs scalar masses within a supersymmetric grand unified framework in which tan beta similar or equal to m(t)(0)/m(b)(0) and the electroweak symmetry is radiatively broken. The requirement that the calculated b quark mass lies close to its measured value, together with the cosmological constraint Omega(LSP) approximate to 1, fixes the top quark mass to be m(t)(m(t)) approximate to 140 - 185 GeV. The LSP (of B-ino purity greater than or similar to 98%) has a mass similar to 200 - 350 GeV. In the scalar Higgs sector the CP-odd scalar mass m(A) less than or similar to 220 GeV. With m(A) greater than or similar to M(Z), as suggested by the decay b --> s gamma, we find M(Z) less than or similar to m(h0)(m(H0)) M less than or similar to 140(220) GeV and 120 GeV less than or similar to m(H+/-) less than or similar to 240 GeV.
