论文摘要
尽管对暗物质的搜索持续了数十年，但是在地下检测，宇宙射线观测和对撞机实验中没有歧义的情况下，没有发现令人信服的信号。我们以示例表明，如果暗物质的产生遵循强大的一阶宇宙学相变，引力波（GW）观察结果可能是暗物质检测的补充。我们在使用CP对称的标准模型的复杂单线扩展中探索了这种可能性。我们展示了三个基准，其中一阶相变的GW信号足以容纳未来的基于空间的GW观测值，例如BBO，U-Decigo，Lisa，Taiji和Tianqin。尽管满足了Xenon1t实验的约束和费米 - 拉特伽马射线观测值，但在这些情况下，质量约为$ \ sim 1 $ 〜TEV的暗物质候选者具有正确的遗物丰度，这是由宇宙微波辐射的Planck观察获得的。
Although searches for dark matter have lasted for decades, no convincing signal has been found without ambiguity in underground detections, cosmic ray observations, and collider experiments. We show by example that gravitational wave (GW) observations can be a supplement to dark matter detections if the production of dark matter follows a strong first-order cosmological phase transition. We explore this possibility in a complex singlet extension of the standard model with CP symmetry. We demonstrate three benchmarks in which the GW signals from the first-order phase transition are loud enough for future space-based GW observations, for example, BBO, U-DECIGO, LISA, Taiji, and TianQin. While satisfying the constraints from the XENON1T experiment and the Fermi-LAT gamma-ray observations, the dark matter candidate with its mass around $\sim 1$~TeV in these scenarios has a correct relic abundance obtained by the Planck observations of the cosmic microwave background radiation.
