Complete Reconstruction of the Neutralino System

Abstract

Consecutively to the chargino system, ${\widetilde{chi}}^{p}m$, in which the SU(2) gaugino parameter $M_2$, the higgsino mass parameter $\mu$ and $\tan \beta$ can be determined, the remaining fundamental supersymmetry parameter, the U(1) gaugino mass $M_1$ can be analysed in the neutralino system, ${\tilde{\chi }}^0$, 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.
