Abstract

We construct a renormalizable, supersymmetric theory of flavor and R parity based on the discrete flavor group (S3)3. The model can account for all the masses and mixing angles of the standard model, while maintaining sufficient squark degeneracy to circumvent the supersymmetric flavor problem. By starting with a simpler set of flavor symmetry-breaking fields than we have suggested previously, we construct an economical Froggatt-Nielsen sector that generates the desired elements of the fermion Yukawa matrices. With the particle content above the flavor scale completely specified, we show that all renormalizable R-parity-violating interactions involving the ordinary matter fields are forbidden by the flavor symmetry. Thus, R parity arises as an accidental symmetry in our model. Planck-suppressed operators that violate R parity, if present, can be rendered harmless by taking the flavor scale to be \ensuremath\lesssim8\ifmmode×\else\texttimes\fi1010 GeV.
