论文摘要
在宇宙学的一阶相变中，在黑暗区域中，费米昂的暗物质颗粒$χ$可以形成宏观的费米球，这些球在某些条件下崩溃至原始黑洞（PBHS）。 PBHS的蒸发会产生增强的$χ$通量，如果$χ$ couples到可见的物质，则可以检测到。我们考虑$χ$与电子的相互作用，并计算Xenon1t，Xenonnt，Super-Kamiokande和Hyper-Kamiokande实验中暗物质通量的信号。可以在Theia和$μ$ ARES上观察到来自相变的相关重力波信号。 CMB-S4可测量的一定数量的暗辐射是相变的epiphenomenon。
During a cosmological first-order phase transition in a dark sector, fermion dark matter particles $χ$ can form macroscopic Fermi balls that collapse to primordial black holes (PBHs) under certain conditions. The evaporation of the PBHs produces a boosted $χ$ flux, which may be detectable if $χ$ couples to visible matter. We consider the interaction of $χ$ with electrons, and calculate signals of the dark matter flux in the XENON1T, XENONnT, Super-Kamiokande and Hyper-Kamiokande experiments. A correlated gravitational wave signal from the phase transition can be observed at THEIA and $μ$Ares. An amount of dark radiation measurable by CMB-S4 is an epiphenomenon of the phase transition.
