Abstract
We report on a search for the excited leptons e, mu*, tau* and nu* in e(+)e(-) collisions at root s = 130-140 GeV using the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected pair produced ll* in the channels ee gamma gamma, mu mu gamma gamma, tau tau gamma gamma, eeWW, and nu nu gamma gamma, We d etermine the lower mass limits at 95% C.L. of 64.7 GeV for e, 64.9 Ge V for mu, 64.2 GeV for tau*, 57.3 GeV (eW decay mode) and 61.4 GeV (n u gamma decay mode) for nu. From an analysis of the expected singly p roduced ll in the channels ee gamma, mu mu gamma, tau tau gamma, nu e W and nu nu gamma, we determine upper limits on the couplings lambda/m (l) up to m(l*) = 130 GeV.
