| Abstract |
A search for charged and neutral excited leptons is performed in 217 pb−1 of e+e−
collision data collected with the L3 detector at LEP at centre-of-mass
energies from 202 up to 209 GeV. The pair- and single-production
mechanisms of excited electrons, muons and taus, as well as of excited
electron-, muon- and tau-neutrinos, are investigated and no signals are
detected. Combining with L3 results from searches at lower
centre-of-mass energies, gives improved limits on the masses and
couplings of excited leptons.
