摘要：

We study the pair productions of neutralinos in the next-to-minimal supersymmetric standard model in the future 500-GeV e(+)e(-) collider. For a reasonable set of parameters that are consistent with the present experimental data, we analyze the productions for different values of the scalar electron mass. The analysis shows that all the neutralinos but the heaviest one may be produced if the scalar electrons do not have masses larger than 1 TeV. The lightest neutralino may be assumed to be the lightest supersymmetric particle, making itself a candidate for the dark matter in the universe. The conditions for the lightest neutralino to account for the dark matter problem is also investigated.
