## A Credible Gauge Field Theory For My Cosmic QCD Axion

*SU*(3) family gauge symmetry and the axion, Thomas Appelquist, Yang Bai and Maurizio Piai, Phys. Rev. D 75, 073005 (5 April 2007), doi:10.1103/PhysRevD.75.073005

We analyze the structure of a recently proposed effective field theory (EFT) for the generation of quark and lepton mass ratios and mixing angles, based on the spontaneous breaking of an

SU(3) family gauge symmetry at a high scaleF. We classify the Yukawa operators necessary to seed the masses, making use of the continuous global symmetries that they preserve. One globalU(1), in addition to baryon number and electroweak hypercharge, remains unbroken after the inclusion of all operators required by standard model fermion phenomenology. An associated vacuum symmetry insures the vanishing of the first-family quark and charged-lepton masses in the absence of the family gauge interaction. If thisU(1) symmetry is taken to be exact in the EFT, broken explicitly by only the QCD-induced anomaly, and if the breaking scaleFis taken to lie in the range 10^{9}–10^{12}GeV, then the associated Nambu-Goldstone boson is a potential QCD axion.

This does seem to fit, but I will have to work through it since things have changed since then.

The Higgs boson and all that. This will take a while to work through.
