摘要：

We extend the Bardeen-Hill-Lindner dynamical electro-weak symmetry breaking model to include the Peccei-Quinn mechanism. We take advantage of the fact that the coupled gap equations admit a critical line, parametrized by a U(1)A-violating coupling, along which m(b)/m(t) stays fixed even for m(b,t) --> 0. A dynamical Dine-Fishler-Srednicki mechanism triggered by a approximately nu(R) nu(R) condensate is constructed, offering novel neutrino-axion physics. U(1)PQ plays then the role of an axial family group.
