Gravitational waves and monopoles dark matter from first-order phase transition
arXiv:2204.07540 · doi:10.1016/j.physletb.2023.137822
Abstract
We study the possibility of monopoles serving as dark matter when they are produced during the first-order phase transition in the dark sector. Our study shows that dark monopoles can contribute only a small piece of dark matter relic density within parameter spaces where strong gravitational waves can be probed by ET and CE, and the monopoles can contribute a sizable component of the observed dark matter relic density for fast phase transitions with short duration.
