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…

Cosmic Strings from Tribrid Inflation
Stefan Antusch, Katarina TrailoviÄ
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…
