Distinguishing Dirac from Majorana Heavy Neutrino at Future Lepton Colliders

Abstract

We propose to identify whether a sterile neutrino is Dirac-type or Majorana-type by counting the peak of the rapidity distribution at lepton colliders. Our method requires only one charged-lepton tagging, and the nature of sterile neutrinos can be pinned down once they are confirmed.
