摘要：

A search for exotic unstable neutral and charged heavy leptons as well as for stable charged heavy leptons; is performed with the L3 detector at LEP Sequential, vector and mirror natures of heavy leptons are considered. No evidence for their existence is found and lower limits on their masses are set. (C) 2001 Published by Elsevier Science B.V.
