Abstract
AbstractThe canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields. The explicit calculation of the instanton‐induced breaking of the Goldstone field direction necessary to derive the canonical axion mass and decay constant relation is presented. The primer is intended to serve an audience with elementary quantum field theory expertise.

4. We remark that the generic nature of Goldstone bosons arising in ultraviolet extensions of the Standard Model can typically be mapped to the field theory at hand although the key requirements to satisfy are that the ultraviolet fields exhibit Goldstones traversing a compact field space and the ultraviolet continuous symmetries are not gauged (Goldstones arising from noncompact continuous symmetries are called dilatons).
