Abstract
A search for pair production of new heavy leptons has been performed a ssuming different scenarios for the mixing of the new particles with S tandard Model leptons. No candidate events were found in a data sample corresponding to an integrated luminosity of 5.6 pb(-1) collected by the ALEPH detector at centre-of-mass energies of 130 and 136 GeV. New limits on production cross-sections and on masses of sequential lepton s were obtained which significantly extend the mass regions excluded a t LEP1. For instance, charged heavy leptons with masses below 63.5 GeV /c(2) are excluded at 95% C.L. for mass differences to the associated neutral lepton of more than 7 GeV/c(2).
