来自一级相变的暗物质的引力波和磁单极

Gravitational waves and monopoles dark matter from first-order phase transition

Jing Yang, Ruiyu Zhou, Ligong Bian

摘要:

我们研究了在暗区一阶相变过程中产生的磁单极子作为暗物质的可能性。我们的研究表明,暗单极子可以只贡献一小块的暗物质遗迹密度的参数空间内,强引力波可以探测到的ET和CE,和单极子可以贡献一个相当大的组成部分,观察到的暗物质遗迹密度的快速相变与短的持续时间。

英文摘要:

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.
