Extending sensitivity for low-mass neutral heavy lepton searches

Academic Article


  • 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 [Formula presented] with a mass [Formula presented] 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 [Formula presented], [Formula presented], [Formula presented], [Formula presented], [Formula presented], and [Formula presented] final states, we use general scaling features to estimate the sensitivity of [Formula presented] searches in current and future experiments, emphasizing the importance of the [Formula presented] decay mode. © 1997 The American Physical Society.
