Spin Effects in Neutralino Production in $e^{+}{e}^{-}$ Annihilation with polarized beams

G. Moortgat-Pick, H. Fraas, A. Bartl +1

We study the process e^+ e^- -> chi^0_1 chi^0_2 and the subsequent decay chi^0_2 -> chi^0_1 l^{+} l^{-}$withpolarizedbeams,includingthecompletespincorrelationsofch{i}_2^0$.…
