论文摘要
如果暗物质（DM）在一阶相变中获得质量，则当DM进入扩展的气泡时，将会产生过滤效果。在本文中，我们研究了伪量表DM的过滤输出效果，其质量可能部分来自隐藏扇区中的一阶相变。我们计算可能进入各种气泡壁速度的气泡的DM和DM的各种状态（在热平衡中或在热量平衡中）的各种状态，这可能会导致较小的渗透率，这可能会影响DM的最终遗物。我们进一步研究了由隐藏的扇形相变发出的随机重力信号在空间基础干涉仪实验中作为该模型的吸烟枪。
If dark matter (DM) acquires mass during a first order phase transition, there will be a filtering-out effect when DM enters the expanding bubble. In this paper we study the filtering-out effect for a pseudo-scalar DM, whose mass may partially come from a first order phase transition in the hidden sector. We calculate the ratio of DM that may enter the bubble for various bubble wall velocities as well as various status of DM (in the thermal equilibrium, or out of the thermal equilibrium) at the time of phase transition, which results in small penetration rate that may affect the final relic abundance of the DM. We further study the stochastic gravitational wave signals emitted by the hidden sector phase transition at the space-based interferometer experiments as the smoking-gun of this model.
