Abstract

Excited neutrinos decaying into a neutrino and a photon are searched for in the ALEPH detector at LEP. No evidence is found for Z decay into nu nu* or nu* nu* final states. Upper limits are derived on excited neutrino couplings up to excited neutrino masses close to the Z mass. Lower limits on the nu* mass, independent of the nu* decay modes, are deduced from the total Z width.
