$\Delta (27)$ framework for cobimaximal neutrino mixing models

Abstract

We propose a simple framework based on $\Delta (27)$ that leads to the successful cobimaximal lepton mixing ansatz, thus providing a predictive explanation for leptonic mixing observables. We explore first the effective neutrino mass operators, then present a specific model realization based on type I seesaw, and also propose a model with radiative 1-loop seesaw which features viable dark matter candidates.
