Third-generation effects on fermion mass predictions in supersymmetric grand unified theories
Third-generation effects on fermion mass predictions in supersymmetric grand unified theories
Relations among fermion masses and mixing angles at the scale of grand unification are modified at lower energies by renormalization group running induced by gauge and Yukawa couplings. In super-symmetric theories, the $b$ quark and $\ensuremath{\tau}$ lepton Yukawa couplings, as well as the $t$ quark coupling, may cause significant running …
