Description
Summary:Abstract Supersymmetric theories supplemented by an underlying flavor-symmetry Gf $$ {\mathcal{G}}_f $$ 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 Gf=Δ27 $$ {\mathcal{G}}_f=\Delta (27) $$, A 4, and S 3.
