Abstract:
Neutrinos may be the harbingers of new dark sectors, since the renormalizable neutrino portal allows for their interactions with hidden new physics. This fact may be used to connect the generation of neutrino masses to a light dark sector, charged under a new U(1)d dark gauge symmetry. By introducing the minimal number of dark fields to obtain an anomaly free theory with spontaneous breaking of the dark symmetry we obtain automatically the inverse seesaw Lagrangian. In addition, the so-called μ-term of the inverse seesaw is dynamically generated and technically natural in this framework. As a bonus, the new light dark gauge boson can provide a possible explanation to the MiniBooNE anomaly.
