摘要：

Excited leptons are searched for using the L3 detector at LEP. The data collected at centre-of-mass energies in the range from 192 up to 202 GeV correspond to a total luminosity of 233 pb(-1). No evidence of either pair production of excited leptons, nor of single production is found. From the searches for pair produced excited leptons, lower mass limits close to the kinematic limit are set. From the searches for singly produced excited leptons, upper limits on their couplings are derived in the mass range up to 200 GeV. (C) 2001 Published by Elsevier Science B.V.
