Abstract: (Elsevier)
We have searched for charged and neutral leptons. We exclude stable Dirac neutrinos below 42.8 GeV and stable Majorana neutrinos below 34.8 GeV. From a search for unstable neutrinos we exclude masses below 46.4 GeV (Dirac) and below 45.1 GeV (Majorana). We exclude all masses of sequential charged and neutral leptons, except if both masses are larger than 42.8 GeV (for stable Dirac neutrinos). All mass limits correspond to 95% CL.
