摘要：

We discuss the abundance of supersymmetric neutralino dark matter incorporating renormalized supergravity relations between sparticle masses in terms of the parameters m0 (scalar mass), m1/2 (gaugino mass), mu (Higgs mixing parameter), m(A) (pseudoscalar Higgs mass) and tan-beta (ratio of Higgs VEVs), in the minimal supersymmetric extension of the standard model. We include radiative corrections to the Higgs boson masses. We describe the regions of the (mu, M2), (m0, M2), (m0, tan-beta), and (m(A), tan-beta) planes where the neutralino could have the critical density.
