摘要：

Excited leptons have been searched for using data recorded by the OPAL detector at LEP. No evidence for such particles has been found. From the study of e+e- → ℓ+ℓ-γγ events, lower limits on the masses of spin- 1 2 excited leptons are found to be 44.9 GeV at 95% confidence level. From the study of e+e- →ℓ+ℓ-γ events, upper limits on their couplings are set up to ℓ* masses close to the mass of the Z0 boson. © 1990.
