Dine, Fischler, and Srednicki have proposed a solution to the strong CP puzzle in which the mass and couplings of the axion are suppressed by an inverse power of a large mass. We construct an explicit SU (5) model in which this mass is the vacuum expectation value which breaks SU (5) down to SU (3) SU (2) U (1).
Wise et al. (Mon,) studied this question.
