Charginos and Neutralinos at e+e- Linear Colliders

Abstract

It is shown how the fundamental gaugino and higgsino parameters of the chargino and neutralino system in the MSSM can completely be determined in high--precision experiments at e+e- linear colliders even if in their initial phase only the light charginos ${\tilde{\chi }}_1^{\pm }$ and the light neutralinos ${\tilde{\chi }}_1^0$ and ${\tilde{\chi }}_2^0$ are kinematically accessible.
