Abstract
We searched for excited electrons and muons from Z0 decay in the channels ee→eeγ, ee→eeγγ, ee→(e)eγ, ee→μμγ, ee→μμγγ. using the L3 detector at LEP. The lower mass limit for e∗ is 45.0 GeV and for μ∗ 45.3 GeV. The upper limits of ℓℓ∗Z0 and ℓℓ∗γ couplings at 95% CL have been determined up to m ℓ∗ close to the Z0 mass.
