Gauge Interaction

As a simple extension, a non-Abelian family gauge symmetry SO(3), as well as three family Majorana neutrinos, was introduced to explain the tri-bimaximal mixing matrix of neutrinos. We discuss the effect of the possible SO(3) family gauge interaction to the mass differences of [Formula: see text] and [Formula: see text], and get the constrains to the new gauge bosons.

Chiral Lagrangian

We calculate the top quark loop corrections to the [Formula: see text] vertex in the chiral Lagrangian of the dynamical electroweak symmetry breaking theory. We use the effective Lagrangian based on coset space SU(2)×U(1)/U(1) with the electroweak gauge interaction switched off, so these corrections are directly related to the physics associated with the heavy top quark and the mass generation in the dynamical models.

Breaking Scale

We examine whether the unification constraints on the Yukawa couplings and on the Higgs masses in the minimal supersymmetric Standard Model can be consistent with the observed mass pattern of the third generation fermions. The effects of the QCD interaction and the SU(2)R breaking owing to the U(1) Y gauge interaction and the absence of ντR are crucial. We observe that the parameter choice of “no-scale” supergravity is favored and the SUSY breaking scale has a lower bound, in order for the top quark to be much heavier than the bottom quark.
