A bstractIn a model proposed in 2012, all flavor mixing has a single source and is governed by a single “master matrix.” This model was shown to give several predictions for quark and lepton masses and mixing angles and for mixing angles within SU(5) multiplets that are observable in proton decay. Here it is shown that the same master matrix controls the flavor-changing processes mediated by a singlet scalar that exists in the model, giving predictions for τ → μγ, τ → eγ, and μ → eγ.

A bstractIt was recently proposed that all flavor mixing has a single source, namely the mixing of the three quark and lepton families with “extra” vectorlike fermions in 5 + $ \overline{5} $… Expand

A bstractIt is proposed that all flavor mixing is caused by the mixing of the three quark and lepton families with vectorlike fermions in $ 5+\bar{5} $ multiplets of SU(5). This simple assumption… Expand

We present a supersymmetric standard model with three gauged Abelian symmetries of a type commonly found in superstrings. One is anomalous; the other two are ${E}_{6}$ family symmetries. It has a… Expand

An analysis of leptonic decays based on unitary symmetry for strong interactions (eightfold way) and the V-A theory for weak interactions is presented. An explanation for the observed predominance of… Expand

A structure is proposed for the mass matrices of the quarks and leptons that arises in a natural way from the assumption that the breaking of SO(10) gauge symmetry is achieved by the smallest… Expand
