Description
Sterile neutrinos may be part of a quasi-hidden sector that interacts with Standard Model particles via a heavy mediator. In the case where two (or more) sterile neutrinos have a flavor-changing coupling to a new boson which also couples to nucleons, the heavier state $N_2$ may decay into the lighter state $N_1$ and a pair of Standard Model particles. If the mass difference between the sterile neutrinos is large enough, the $N_2 \to N_1 \pi^+ \pi^-$ process can lead to striking signatures at neutrino detectors. In particular, the light sterile neutrino may be produced through oscillations and then up-scatter creating a pion pair in the detector which is displaced from a DIS event.
