Neutrino Masses from a Dark Neutrino Sector below the Electroweak Scale

Abstract

We consider a minimal extension of the Standard Model which advocates a dark neutrino sector charged under a hidden $U(1{)}^{\prime }$. 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.
