Axion mass in the case of post-inflationary Peccei-Quinn symmetry breaking

Abstract

The axion not only solves the strong CP puzzle, but it also may be the main constituent of cold dark matter. We review the axion dark matter predictions for the case that the Peccei-Quinn symmetry is restored after inflation.
