摘要

As a next step in the exploration of a class of flavored gauge mediation models of supersymmetry breaking in which the mixing of the Higgs and messenger doublets are connected by a discrete non-Abelian symmetry, we investigate the generation of nontrivial mass hierarchies and mixing angles for the Standard Model matter fields. We consider here the case in which the Higgs-messenger symmetry, which we take for concreteness to be the discrete group S 3 , also plays the role of a (partial) family symmetry. Within the specific implementation of S 3 studied here, we show that couplings at the renormalizable level can result in hierarchical quark masses, but do not lead to phenomenologically viable quark mixing parameters, requiring the inclusion of higher-dimensional operators. As a concrete exploration of this idea, we show that the Cabibbo angle can be generated within this framework via such nonrenormalizable couplings and explore the phenomenological implications of this scenario.
