HERNANDEZ GALEANA, A.. Radiative generation of light fermion masses in a SU(3)_H horizontal symmetry model. Rev. mex. fis. [online]. 2004, vol.50, n.5, pp.522-526. ISSN 0035-001X.

In a model with a gauge group SU(3)_H ⊗ G_SM, where SU(3)_H is a horizontal symmetry and G_SM = SU(3)_C ⊗ SU(2)_L ⊗ U(1)_Y is the standard model, we propose a radiative mechanism of mass generation mediated by the SU(3)_H gauge bosons for the light fermions, meanwhile the masses of the heaviest family are generated by the implementation of see - saw mechanisms with the introduction of vectorial fermions.

Keywords : Horizontal symmetry; fermion masses.
