Query: A Fundamental QCD Axion Model   We construct and study a fundamental field theory of the QCD axion: all
couplings flow to zero in the infinite-energy limit realizing the totally
asymptotically free (TAF) scenario. Some observable quantities (such as the
masses of new quarks and scalars) are predicted at low energies by the TAF
requirement in terms of gauge couplings and a vector-boson mass. Here the
minimal model of this sort is explored; the axion sector is charged under an
SU(2) gauge group and a dark photon appears at low energies. This model can be
TAF and feature an absolutely stable vacuum at the same time.
