Production of Axions by Cosmic Magnetic Helicity
arXiv:astro-ph/0512458 · doi:10.1103/PhysRevLett.96.161302
Abstract
We investigate the effects of an external magnetic helicity production on the evolution of the cosmic axion field. It is shown that a helicity larger than (few \times 10^{-15} G)^2 Mpc, if produced at temperatures above a few GeV, is in contradiction with the existence of the axion, since it would produce too much of an axion relic abundance.
