Understand

It is shown that in supersymmetric SU(N) models with N>5 the so-called doubly lopsided mass matrix structure can emerge in a natural way.

The non-trivial flavor structure is entirely accounted for by the SU(N) gauge symmetry and supersymmetry, without any flavor symmetry.
The hierarchy among the families results directly from a hierarchy of scales in the chain of breaking from SU(N)to the Standard Model group.
A simple SU(7) example is presented.
