Abstract

We show that the seesaw neutrino mass mechanism call coexist naturally with all extended gauge symmetry (i.e. without any gauge hierarchy problem) provided that the gauge symmetry contains gauged lepton number differences. The simplest such "natural" seesaw models are constructed and their implications for neutrino anomalies discussed. © World Scientific Publishing Company.
