Abstract

Abstract It is shown that heavy sterile neutrinos can be a consequence of a new broken U(1)X symmetry. This sterile symmetry is further speculated to be related to the conservation of the dark number associated with Dark Matter particles, corresponding to a dark neutrino mass m N D ⩾ 1 keV with a high scale ⩾ ∼ 10 2 GeV dark symmetry U(1)D breaking.
