Phys. Rev. D 56, 2970–2981 (1997)Extending sensitivity for low-mass neutral heavy lepton searchesReceived 17 March 1997; published in the issue dated 1 September 1997 We point out the importance of two-body final states of weak isosinglet neutral heavy leptons predicted in several models of new physics beyond the standard model. We concentrate on muon-type neutral heavy leptons Lμ0 with a mass M<2 GeV that can be searched for with increased sensitivity at a new round of neutrino experiments at CERN and Fermilab. Providing explicit decay rate formulas for the eeν, eμν, μμν, πμ, ρμ, and a1μ final states, we use general scaling features to estimate the sensitivity of Lμ0 searches in current and future experiments, emphasizing the importance of the πμ decay mode. © 1997 The American Physical Society URL:
