论文摘要
我们提出了一种通过一阶电子相变（FOEWPT）形成原始黑洞（PBH）的机制。 FOEWPT是通过用真实的单线标量扩展标准模型来实现的，而PBH的形成是通过称为费米 - 球的非孤子孤子崩溃来实现的。这种孤子是通过在泡沫期间将fermions捕获在虚假真空中的，由于Yukawa内部的吸引力，它们最终倒入PBH。我们证明可以存在具有PBH暗物质候选者的场景，并且典型的实验信号包括FOEWPT重力波和LHC的多勒普顿/JET或流离失所的顶点最终状态。
We propose a mechanism that forms primordial black holes (PBHs) via a first-order electroweak phase transition (FOEWPT). The FOEWPT is realized by extending the Standard Model with a real singlet scalar, while the PBH formation is achieved by the collapse of non-topological solitons called Fermi-balls. Such solitons form via trapping fermions in the false vacuum during the FOEWPT, and they eventually collapse into PBHs due to the internal Yukawa attractive force. We demonstrate that a scenario with PBH dark matter candidate can exist, and the typical experimental signals include FOEWPT gravitational waves and the multi-lepton/jet or displaced vertex final states at the LHC.
