Abstract
We consider a minimal extension of the Standard Model which advocates a dark neutrino sector charged under a hidden U(1)'. We show that neutrino masses can arise radiatively in this model. The observed values are compatible with a light dark sector below the electroweak scale and would imply new heavy fermions which may be testable in the next generation of beam dump searches at DUNE, NA62 and SHIP.File in questo prodotto:
