Scalar particle spectrum in broken fermion family symmetries

We study the spectrum and possible observability of Higgs-like scalar particles associated with spontaneous breaking at high energies of fermion family symmetries such as \(SU(3)_f\) proposed sometime ago by King and Ross. We treat the energy scale at which the symmetry is broken as a variable not necessarily as high as the GUT scale used by King and Ross. We compare and contrast a non-supersymmetric treatment of the fermion family symmetry model introduced here, and the supersymmetric treatment used by King and Ross.
