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。我们专注于通过一个非阿贝尔群扩展标准模型规范对称性的理论，在这个理论下，轻子与新的费米子伙伴形成双重态，其中一个是暗物质候选者。这种新对称性的破缺发生在高尺度上，并导致了早期宇宙中强烈的一级相变。该模型适应了非对称暗物质环境中的重子发生，并预测了在不久的将来实验范围内的引力波信号。
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.
