18. Conclusions Lepton number violation can occur naturally at♦
Lepton number violation can occur naturally at
the TeV scale consistent with unification, dark
matter, and neutrino mass limits ♦
Neutrinoless double beta decay is prominent
and within experimental reach ♦
Simple symmetries can explain the vector-particle
masses, including the mu term ♦
D mixing and mu to e gamma are other tests of the
Specific model
