引力波中的非对称暗物质

Asymmetric Dark Matter from Gravitational Waves

Bartosz Fornal, Erika Pierre

摘要:

我们研究了通过引力波特征探测非对称暗物质模型的前景。我们集中在一个理论扩展标准模型规范对称性的非阿贝尔群,轻子形成与新的费米子伙伴,其中之一是一个暗物质候选人的双重。这种新对称性的破缺发生在高尺度上,并导致早期宇宙中强烈的一级相变。该模型适应重子发生在一个不对称的暗物质设置和预测的引力波信号在不久的将来的实验范围内。

英文摘要:

We investigate the prospects for probing asymmetric dark matter models through their gravitational wave signatures. We concentrate on a theory extending the Standard Model gauge symmetry by a non-Abelian group, under which leptons form doublets with new fermionic partners, one of them being a dark matter candidate. The breaking of this new symmetry occurs at a high scale, and results in a strong first order phase transition in the early Universe. The model accommodates baryogenesis in an asymmetric dark matter setting and predicts a gravitational wave signal within the reach of near-future experiments.
