论文摘要
早期宇宙中的一阶相变的虚假真空残余物可以形成紧凑的物体，这可能构成暗物质。这种残留物形成是因为颗粒之间存在巨大的质量间隙，并在旧阶段被困。我们专注于在具有捕获的黑暗区域颗粒的一类模型中产生的残余物，追踪其发展并确定其最终命运。根据模型和相变参数，这些残余物的进化终点可以是原始的黑洞，费米 - 球，Q球或热球，并且它们都有可能构成一定部分或整个暗物质在广泛的质量范围内。值得注意的是，黑暗扇形热球可以在高温下保持在高温下，并且是一种新的紧凑型暗物质候选者，它是从内部颗粒的热能而不是其质量或量子压力的。
False vacuum remnants in first-order phase transitions in the early Universe can form compact objects which may constitute dark matter. Such remnants form because particles develop large mass gaps between the two phases and become trapped in the old phase. We focus on remnants generated in a class of models with trapped dark sector particles, trace their development, and determine their ultimate fate. Depending on model and phase transition parameters, the evolutionary endpoint of these remnants can be primordial black holes, Fermi-balls, Q-balls, or thermal balls, and they all have the potential to constitute some portion or the whole of dark matter within a broad mass range. Notably, dark sector thermal balls can remain at high temperatures until the present day and are a new compact dark matter candidate which derives its energy from the thermal energy of internal particles instead of their mass or quantum pressure.
