    Description
    The production and subsequent decays of Neutralinos (Majorana fermions) and Charginos (Dirac fermions) are studied in the energy range of LEP2, a future linear collider, and a muon collider. The influence of spin correlations on energy and different angular distributions is discussed. It is demonstrated how spin correlations and polarization effects can be used to determine SUSY parameters at a LC. In this context the polarization of both beams turns out to be important. Sum rules for the cross sections of the neutralino system valid at high energies are presented, which allow a sensitive test of the MSSM.
