Search for neutral heavy leptons in DELPHI
Weak isosinglet neutral heavy leptons ( nu /sub m/) has been searched for in leptonic decays of hadrons and in neutrino beam experiments, leading to stringent upper limits on U /sup 2/ reaching 10/sup -7/ in the low mass region (m/sub nu -m/ below 2-3 GeV/c/sup 2/). OPAL and L3 have also placed limi...
