Search for excited leptons at LEP
Physics Letters B 568,1-2 (2003) 23-34;
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. (C) 2003 Published by Elsevier B.V.
