Abstract

A search was made in 29-GeV e+e- annihilations for massive neutrinos decaying to eX() where X is a muon or meson. A 300-pb-1 data sample yielded just one candidate event with a mass meX>1.8 GeV. Significant limits are found for new neutrinos with masses from 1.8 to 6.7 GeV and with mixing parameters in the range 3×10-6<U2<1.. AE.
