Abstract: | We examine and compare implications of several recent suggestions that events of the form could be due to unusual Z0 decays. Two possibilities are noted: (a) , where N (or ) is a neutral heavy lepton decaying to three neutrinos with a 10% branching ratio, and (b) Z0→h1h2, where h1 and h2 are two distinct spinless particles, and only the decay of h1 is seen in the detector. Early tests of both possibilities are noted. |
