Abstract. We study the production of neutralinos $e^+ e^- \to\tilde{\chi}^{0}_i\tilde{\chi}^{0}_j$ with polarized beams and the subsequent decays $\tilde{\chi}^{0}_{i} \to \tilde{\chi}^0_k\ell^{+}\ell^{-}$ and $\tilde{\chi}^{0}_{j} \to \tilde{\chi}^0_l \ell^{+}\ell^{-}$, including the complete spin correlations between production and decay. We present analytical formulae for the differential cross section of the combined process of production and decay of neutralinos. We also allow for complex… CONTINUE READING
