Partial compositeness can be used to explain the fermion mass hierarchy and predict the sfermion mass spectrum in a supersymmetric model. It assumes that the Higgs and third-generation matter superfields are elementary fields, while the first two matter generations are composite, with a linear mixing between elementary superfields and supersymmetric operators with large anomalous dimensions.
This then gives rise to a split-like supersymmetric model that explains the fermion mass hierarchy while simultaneously predicting an inverted sfermion mass spectrum with a gravitino LSP that is consistent with LHC and flavor constraints. The model therefore intricately connects the sector responsible for the generation of flavor with supersymmetry breaking to produce a unique sparticle spectrum.
