SPIN EFFECTS IN NEUTRALINO PRODUCTION IN E(-) ANNIHILATION WITH POLARIZED BEAMS()E()

We study the process e(+)e(-) --> <(chi)over tilde>(0)(1)<(chi)over ti lde>(0)(2) and the subsequent decay <(chi)over tilde>(0)(2) --> <(chi) over tilde>(0)(1)l(+)l(-) with polarized beams, including the complete spin correlations of <(chi)over tilde>(0)(2). We present numerical re sults for the lepton energy and angular distributions, and for the dis tribution of the opening angle between the leptons for root s = 500 Ge V. The effects of spin correlations are important in the lepton angula r distribution, especially for gaugino-like neutralinos. The opening a ngle distribution is particularly suitable for distinguishing between higgsino- and gaugino-like neutralinos. The polarized cross sections a nd lepton angular distributions are very sensitive to the mixing of th e neutralinos.
