Search for excited leptons in e(+)e(-) collisions at root s=161 GeV

Abstract:

A search with the DELPHI detector at LEP for excited leptons (e*, μ*, τ* and v*) decaying through γ, W or Z transitions is reported. The data used correspond to an integrated luminosity of 10 pb-1 at an e+e- centre-of-mass energy of 161 GeV. The search for pair produced excited leptons established the limits me* > 79.6 GeV/c2, mμ* > 79.6 GeV/c2, mτ* > 79.4 GeV/c2 and mv* > 56.4 GeV/c2 at 95% confidence level, assuming that the SU(2) and U(1) couplings of excited leptons are in the...
