论文摘要
在过去的几十年中，弱相互作用的巨大颗粒（WIMP）一直是最流行的粒子暗物质（DM）候选者，众所周知，可以通过直接，间接和对撞机的实验探测WIMP。但是，在某些标量介导的DM模型中，直接和间接信号高度抑制了，例如Lepton Portal模型，带有Majorana DM候选人。结果，对撞机搜索被认为是探究此类模型的唯一希望。在这份白皮书中，我们提出，重力波（GW）天文学也是通过潜在的一阶相跃迁GW信号探测此类标量介导的WIMP模型的强大工具。提供了Lepton Portal暗物质的一个示例，显示了对撞机和GW探针之间的互补性。
The weakly interacting massive particles (WIMPs) have been the most popular particle dark matter (DM) candidate for the last several decades, and it is well known that WIMP can be probed via the direct, indirect and collider experiments. However, the direct and indirect signals are highly suppressed in some scalar-mediated DM models, e.g. the lepton portal model with a Majorana DM candidate. As a result, collider searches are considered as the only hope to probe such models. In this white paper, we propose that the gravitational wave (GW) astronomy also serves as a powerful tool to probe such scalar mediated WIMP models via the potential first-order phase transition GW signals. An example for the lepton portal dark matter is provided, showing the complementarity between collider and GW probes.
