Popis: A search was made in 29 GeV e+e− annihilations for heavy, neutral leptons decaying to e±X∓(ν), where X is a muon or charged meson. Six events with isolated e±X∓ pairs were found for an intergrated luminosity of 106 pb−1. The expected background is 5.5 ± 2.2 events. Limits on σ s B depend on mass and range from 8 to 20 × 10−5 nb.
