In the context of , where
comes from
, supplemented by the non-Abelian discrete
symmetry for three lepton families, Dirac neutrino masses and their mixing are radiatively generated through dark matter. The gauge
symmetry is broken spontaneously. The discrete
symmetry is broken softly and spontaneously. Together, they result in two residual symmetries, a global
lepton number and a dark symmetry, which may be
,
, or
depending on what scalar breaks
. Cobimaximal neutrino mixing, i.e.
,
, and
, may also be obtained.
