    • This mechanism for interfamily mass hierarchy was also noted by S. Barr, Phys. Rev. D 42, 3150 (1990). In this work the vectorlike families were assumed to have GUT scale masses, which would not be relevant for present discussions.

    • Masses and mixings of the first family fermions (in the hat basis) are attributed to higher dimensional operators consistent with flavor symmetries which directly provide entries of order 1 MeV in the 3 × 3 sector involving the chiral families.

    • f would typically be cancelled either by the presence of other massless fields or by the Green-Schwarz mechanism. Vanishing of the D term of an anomalous U(1) can generically induce GUT scale VEVs of certain fields (such as X and X′) without a superpotential for such fields.
