Abstract
Supersymmetric theories supplemented by an underlying flavor-symmetry \( {\mathcal{G}}_f \) provide a rich playground for model building aimed at explaining the flavor structure of the Standard Model. In the case where supersymmetry breaking is mediated by gravity, the soft-breaking Lagrangian typically exhibits large tree-level flavor violating effects, even if it stems from an ultraviolet flavor-conserving origin. Building on previous work, we continue our phenomenological analysis of these models with a particular emphasis on leptonic flavor observables. We consider three representative models which aim to explain the flavor structure of the lepton sector, with symmetry groups \( {\mathcal{G}}_f=\Delta (27) \), A4, and S3.

We report an error in the soft mass matrices due to the values of the flavons in the Δ(27) model taken as an example in our work [1] (section 3).
