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 $\tildeχ^\pm_1$ and the light neutralinos $\tildeχ^0_1$ and $\tildeχ^0_2$ are kinematically accessible.
