Contribution

It introduces a new model utilizing Delta(27) symmetry to realize geometric spontaneous CP violation in neutrino physics.

Abstract

Predictive spontaneous CP violation is possible if it is obtained geometrically through a non-Abelian discrete symmetry. I propose such a model of neutrino mass and mixing based on Delta(27).
