Abstract

A search for excited lepton production in e+ e- collisions was performed using the data collected by the DELPHI detector at LEP at centre-of-mass energies ranging from 189 GeV to 209 GeV, corresponding to an integrated luminosity of approximately 600 pb-1. No evidence for excited lepton production was found. In searches for pair-produced excited leptons. lower mass limits were established in the range 94-103 GeV/c 2 , depending on the channel and model assumptions. In searches for singly-produced excited leptons, upper limits on the parameter f/Δ were established as a function of the mass.
