RESUMO
There is new experimental evidence which may be interpreted as a small departure from quark-lepton universality. We propose to understand this as the result of a hierarchy of mass scales in analogy to m u, m d << L QCD for strong isospin. We show <

in principle, but all are still approximately equal. New physics is predicted at the TeV scale.
