| Abstract | A search for the radiative decay of excited leptons, and for the weak decay of excited electron neutrinos was undertaken using the 21.8pb-1 of data collected by ALEPH at 161-172 GeV. No evidence for a signal was found in single or pair production. Excluded mass limits from pair production are close to 85 GeV/c2 for excited charged leptons and 80.5 GeV/c2 for excited neutrinos. Limits on the couplings of excited leptons were derived from single production. |
