Abstract
We compute, as functions of the relevant parameters of the underlying supersymmetric theory, the contribution from the Z 0-boson decays into neutralino pairs to (i) the Z 0-total width, (ii) the “neutrino-counting” cross section σ(e +e −→γ+missing energy), (iii) events with very characteristics missing energy signatures, arising from the decays of heavier neutralinos. Clear signals are expected for an important range of supersymmetric parameters, not otherwise easily explorable
