Search for pair production of unstable heavy leptons in $e^{+}e^{-}$ collisions at centre-of-mass energies of 161 and 172 GeV
The data collected at 161 and 172 GeV by ALEPH at LEP, corresponding to an integrated luminosity of about 22 pb-1, are analysed in a search for pair-production of heavy leptons. No evidence for a signal was found. New limits on production cross-sections and on masses of sequential leptons are set, w...
