Descripción
A search for excited leptons e*, μ* , τ∗ and ντ∗ in e+e-collisions at √s = 161 GeV is performed using the 10.8 pb⁻¹ of data collected by the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected ℓ*ℓ* pair production in the channels eeγγ, μμγγ, ττγγ, eeWW, and ννγγ, the lower mass limits at 95% C.L. are 79.7 GeV for e*, 79.9 GeV for μ*, 79.3 GeV for τ∗ and 71.2 GeV for ντ∗ assuming the same couplings as for standard leptons. From an analysis of the expected ℓℓ* single production in channels eeγ, μμγ, ττγ, νeeW and ννγ, the upper limits on the couplings λmℓ* up to mℓ= 161 GeV are determined.
