Generalized CP symmetries in Delta(27) flavor models

Abstract

We classify explicitly all the possible generalized CP (GCP) symmetries that are definable in $\Delta (27)$ flavor models. In total, only 12 transformations are possible. We also show interesting consequences of considering some of them as residual symmetries of the neutrino sector.
