论文摘要
来自一阶相变(FOPT)的原始黑洞(PBH)形成结合了超越标准模型物理的两个普遍元素,并具有广泛的后果。我们详细阐述了最近提出的方案,在这种情况下,真空能量衰减种子中的不均匀性过度崩溃至PBHS。在这种情况下,PBH质量由Hubble质量确定,如常规形成方案,而其数量密度是由FOPT的成核动力学决定的。我们提出了一项关于包括参数依赖性(包括参数依赖性)的形成概率的详细研究。此外,我们在开放式质量窗口以及HSC和OGLE候选微透镜事件中生成种群。这种机制不可避免地会在通用FOPT中产生PBH,并在缓慢和中等强的相变产生大量人群。
Primordial black hole (PBH) formation from first-order phase transitions (FOPTs) combines two prevalent elements of beyond the Standard Model physics with wide-ranging consequences. We elaborate on a recently proposed scenario in which inhomogeneities in vacuum energy decay seed the overdensities that collapse to PBHs. In this scenario, the PBH mass is determined by the Hubble mass as in conventional formation scenarios, while its number density is determined by the nucleation dynamics of the FOPT. We present a detailed study of the formation probability including parameter dependencies. In addition, we generate populations in the open mass window as well as for the HSC and OGLE candidate microlensing events. This mechanism inevitably creates PBHs in generic FOPTs, with significant populations produced in slow and moderately strong phase transitions.
