Description
We consider the possibility that heavy neutrinos of low-scale seesaw mechanisms couple to a dark photon in the hidden sector.
These models contain a rather unexplored set of signatures, and as I will discuss, may provide a solution to the 4.8 sigma excess of electron-like events at MiniBooNE. We will see that the dark photon in this model is a semi-visible particle, which is the last type of explanation to the muon (g-2) puzzle based on kinetic mixing that is allowed by data. I will end with a discussion of the future searches for the semi-visible dark sector at kaon, neutrino, and e+e- collider experiments.
