Discovering heavy neutrino-antineutrino oscillations at the -pole
Stefan Antusch, Jan Hajer, Bruno M. S. Oliveira
Collider-testable type I seesaw extensions of the Standard Model are generally protected by an approximate lepton number (LN) symmetry. Consequently, they predict pseudo-Dirac heav…

Heavy neutrino-antineutrino oscillations at the FCC-ee
Stefan Antusch, Jan Hajer, Bruno M. S. Oliveira
We discuss the impact of heavy neutrino-antineutrino oscillations (NNOs) on heavy neutral lepton (HNL) searches at proposed electron-positron colliders such as the future circular…
