QCD Axion Star Collapse with the Chiral Potential
arXiv:1702.05504 · doi:10.1007/JHEP06(2017)014
Abstract
In a previous work, we analyzed collapsing axion stars using the low-energy instanton potential, showing that the total energy is always bounded and that collapsing axion stars do not form black holes. In this paper, we provide a proof that the conclusions are unchanged when using instead the more general chiral potential for QCD axions.
