Domain Walls from $\Sigma (36\times 3)$, $\Delta (54)$ and $\Delta (27)$ potentials

Abstract

We consider the degenerate minima arising from scalar potentials invariant under $\Sigma (36\times 3)$, or under its subgroups $\Delta (54)$ and $\Delta (27)$ (with or without imposed CP symmetries), for a triplet of those symmetries. In this framework, we classify the distinct Domain Walls between the degenerate minima and calculate the respective tensions.
