Axion Cosmology

Open access
Sikivie, Pierre·2008·Lecture Notes in Physics

Abstract

The cosmological properties of axions are reviewed .W e discuss the axions produced by thermal processes in the early universe, the evolution of the av- erage axion field between the Peccei-Quinn and QCD phase-transitions, the domain- wall problem and its possible resolutions, the population of cold axions produced by vacuum realignment, string decay and domain wall decay, and, finally, axion miniclusters and axion isocurvature perturbations. For background information on the strong CP problem and on laboratory and astrophysical axion constraints, the reader is referred to Chaps. 1 and 3. In this chapter, we will be concerned only with the cosmological properties of axions. We merely mention that different authors may use different definitions of the axion decay constant fa. We define normalization by the action density for QCD plus an axion LQCD+a = − 1 G b G bμν + 1 ∂μ a∂ μ 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.
