摘要：
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) < < A(QCD) for strong isospin. We show (G(F))(tq)(NC) < (G(F))(tq)(CC) < (G(F))(ll)(CC) < (GF)(ll)(NC) in principle, but all are still approximately equal. New physics is predicted at the TeV scale.
