Quark masses and mixings in the 3-3-1 model with neutral leptons based on D (4) flavor symmetry

摘要

The D (4) flavor model based on SU(3) (C) aSuSU(3) (L) aSuU(1) (X) gauge symmetry that aims at describing quark mass and mixing is updated. After spontaneous breaking of flavor symmetry, with the constraint on the Higgs vacuum expectation values (VEVs) in the Yukawa couplings, all of quarks have consistent masses, and a realistic quark mixing matrix can be realized at the first order of perturbation theory.
