Abstract

Consecutively to the chargino system, chipm, in which the SU(2) gaugino parameter M2, the higgsino mass parameter μ and β can be determined, the remaining fundamental supersymmetry parameter, the U(1) gaugino mass M1 can be analysed in the neutralino system, χ0, including its modulus and phase in CP--noninvariant theories. First experimental hints on CP violation can be seen in the threshold behaviour of neutralino production.
