摘要：

We examine various solutions of the strong-CP problem to determine their sensitivity to possible violations of global symmetries by Planck scale physics. While some solutions remain viable even in the face of such effects, violations of the Peccei-Quinn (PQ) symmetry by non-renormalizable operators of dimension less than 10 will generally shift the value of thetaBAR to values inconsistent with the experimental bound thetaBAR less than or similar 10(-9). We show that it is possible to construct axion models where gauge symmetries protect the PQ symmetry to the requisite level.
