摘要：
We study in detail the neutralino mass matrix in the minimal extension of the minimal supersymmetric Standard Model. The model contains a Higgs singlet besides the two Higgs doublets of the minimal model. A number of limiting cases are considered wherein the neutralino mass spectrum can be analytically obtained. Based on these analytical results several useful approximation formulas for the neutralino masses are obtained. Using the constraints from the renormalization group analysis of the model, we obtain the spectrum numerically and study the dependence of the neutralino masses on the parameters of the model. We compare the results of the approximation formulas with the numerical results, and thereby establish the applicability of the these formulae in the different regions of the parameter space.
