Descripción
We will discuss the possibility of sterile neutrinos arising as supersymmetric partners of pseudo-Goldstone bosons of a spontaneously broken global symmetry. We will consider both the case of an eV-scale sterile neutrino that could be relevant for the experimental anomalies or for future searches for sterile neutrinos, and the case of a neutrino in the 1 GeV -1 TeV mass range that could be accessible at the LHC or at future collider experiments like the ILC or FCC-ee. In the case of an eV-scale sterile neutrino, we find some correlations between the sterile neutrino mass and the active-sterile mixing angles, such that only a part of the parameter space suggested by the Gallium and reactor anomalies is allowed.
