Abstract
We derive a number of approximate analytical formulas for the neutralino masses and neutralino states in the nominimal supersymmetric standard model containing a Higgs singlet in addition to the two Higgs doublets of the minimal model. A comparison with the numerical solution for the neutralino masses shows that these formulas serve as an excellent approximation for almost the entire phenomenologically interesting range of parameters.
