Abstract

In anomaly free gauged three-flavor SU(3)_f x SU(2)_L x U(1)_Y model of Yanagida with fermion and gauge boson masses described by conveniently chosen elementary scalar Higgs fields the neutrino mass matrix comes out in the seesaw form. Following Yanagida's suggestion we demonstrate that no Higgs fields are needed. Strong flavor gluon interactions themselves, treated in a separable approximation, result in universally split lepton and quark masses calculated in terms of a few parameters. While the realistic splitting of charged lepton and quark masses requires the electroweak and QCD radiative corrections the neutrino seesaw mass matrix comes out exact.
