Charged fermion masses with Yukawa coupling strength universality Original Research Article

We consider the problem of the ordinary charged fermion mass patterns in the framework of a version of the 3-3-1 electroweak gauge model which includes charged heavy leptons. The masses of the top and the bottom quarks are given at the tree level. All the other charged fermion get their masses at the one loop level. The Yukawa coupling strength can be universal. The model is compatible with a mechanism for neutrino mass generation proposed by other authors.
