Phys. Rev. Lett. 59, 1397–1400 (1987)Search for neutral heavy leptons from ν - N scatteringReceived 9 January 1987; published in the issue dated 28 September 1987 Results are presented on a search for neutral heavy leptons that couple to muon neutrinos in high-energy neutrino-nucleon interactions (Eν=30–230 GeV). No evidence for such particles is observed. We obtain upper limits on the coupling of neutral neavy leptons to νμ below Fermi strength in the mass range 0.25–14 GeV/c2. © 1987 The American Physical Society URL:
