Planck-scale corrections to axion models
Abstract
It has been argued that quantum gravitational effects will violate all nonlocal symmetries. Peccei-Quinn symmetries must therefore be an "accidental" or automatic consequence of local gauge symmetry. Moreover, higher-dimensional operators suppressed by powers of ${M}_{\mathrm{Pl}}$ are expected to explicitly violate the Peccei-Quinn symmetry. Unless these operators are of dimension $d\ensuremath{\ge}10$, axion models do not solve the strong $\mathrm{CP}$ problem in a natural fashion. A small gravitationally induced contribution to the axion mass has little if any effect on the density of relic axions. If $d=10,11,or 12$ these operators can solve the axion domain-wall problem, and we describe a simple class of Kim-Shifman-Vainshtein-Zakharov axion models where this occurs. We also study the astrophysics and cosmology of "heavy axions" in models where $5\ensuremath{\le}d\ensuremath{\le}10$.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
