Mass limits for excited electrons and muons from Z 0 decay

We searched for excited electrons and muons from Z 0 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 ∗Z 0 and ℓℓ ∗γ couplings at 95% CL have been determined up to m ℓ...
