Axion String Constraints
Open accessAbstract
We study the production of cosmological axions in the standard scenario in which a global string network forms at the Peccei-Quinn phase transition. We make detailed calculations of the axions produced by string loops, comparing these with estimates of other contributions from long strings and domain walls. We delineate key uncertainties in string network evolution, the chief of which is the magnitude of radiative backreaction. We conclude that axions produced by these topological contributions provide the significant cosmological constraint on the symmetry breaking scale ${f}_{a}$ and the axion mass ${m}_{a}$.

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.
