The production and subsequent decay of spin-0 electrons and muons in e+e- annihilation leads to distinctive noncoplanar e+e- or μ+μ- production, with missing energy carried away by photinos or goldstinos. We give the cross section predicted by supersymmetry for creating pairs of these new spin-0 particles. Present e+e- annihilation experiments imply that their masses must be larger than 3 1 2GeV/c2, and in the near future PETRA experiments will either observe them or raise this limit to ∼15 GeV/c2.
