Search for New Charged Leptons Decaying Into Massive Neutrinos and New Stable Charged Leptons in $e^+ e^-$ Collisions

A search for sequential charged leptons decaying into massive neutrinos has been performed at Ec.m.=56 GeV at the KEK colliding-beam accelerator TRISTAN. We have found no evidence for the production of the charged heavy leptons for an integrated luminosity of 5.3 pb−1. A search for stable charged leptons was also conducted yielding null results. A new mass limit on the charged heavy leptons was obtained as a function of the mass of the associated neutrinos.
