Contributed talk Astro/Cosmo/Neutrinos Astro-Neutrino 1


Lucien Heurtier (U Brussels)


In this talk I will present a model in which large lepton flavour violation in the context of a type I seesaw model is generated. The model incorporates neutrino masses generation as well as a dark matter candidate among the sterile neutrino spectrum, the underlying leptonic symmetry rendering the latter naturally stable. We present a complete phenomenological study of the flavour violation sector which will be tested in the next generation experiments. As a matter of fact, the model contains as well a massive scalar coupling to active neutrinos, that is to be constrained by energy loss of supernovae explosions through scalar particle production. I will hence present a generic update of such constraints for massive scalars and potential indirect signatures of such model through the study of supernovae explosions luminosity curve, high energetic neutrinos detection, etc.
