Lepton number violation at hadron colliders via pseudo-Dirac heavy neutral leptons
Stefan Antusch, Jan Hajer, Bruno M. S. Oliveira
Symmetry-protected low-scale seesaw models can account for the observed neutrino flavour oscillations without fine-tuning, while yielding collider-accessible signatures through pse…
Gravity-assisted neutrino masses
Stefan Antusch, Salvador Centelles Chuliá, Miguel Levy
Gravity is generally expected to violate global symmetries, including lepton number. However, neutrino masses from the Planck-suppressed Weinberg operator are typically too small t…
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…
Explaining PTA Results by Metastable Cosmic Strings from SO(10) GUT
Stefan Antusch, Kevin Hinze, Shaikh Saad
In a recent paper (see https://doi.org/10.1103/PhysRevD.108.095053), we have demonstrated that the 2023 PTA results, which hint at a stochastic gravitational wave (GW) background a…
Cosmic Strings from Tribrid Inflation
Stefan Antusch, Katarina Trailović
Tribrid inflation is a class of supersymmetric inflation models where the scalar component of a matter superfield, or a -flat direction of matter fields, drives inflation. Simil…
Probing SUSY at Gravitational Wave Observatories
Stefan Antusch, Kevin Hinze, Shaikh Saad +1
Under the assumption that the recent pulsar timing array evidence for a stochastic gravitational wave (GW) background at nanohertz frequencies is generated by metastable cosmic str…
