论文摘要
原始黑洞的最终质量分布对功率谱可访问的尺度上的宇宙状态方程敏感。通过在标准模型理论之外的几种超出标准模型理论中存在相变的动机，其中有些是强烈耦合的，我们分析了这种相变的原始黑洞的产生，我们使用量规/重力二元性进行对其进行建模。我们将重点放在（通常被认为是物理上无趣的）情况下，而相变只是平稳的跨界。我们在[10^{ - 16}，10^{ - 6}] m _ {\ odot} $中找到了原始黑洞生产的增强。
The final mass distribution of primordial black holes is sensitive to the equation of state of the Universe at the scales accessible by the power spectrum. Motivated by the presence of phase transitions in several beyond the Standard Model theories, some of which are strongly coupled, we analyze the production of primordial black holes during such phase transitions, which we model using the gauge/gravity duality. We focus in the (often regarded as physically uninteresting) case for which the phase transition is just a smooth crossover. We find an enhancement of primordial black hole production in the range $M_{\rm{PBH}}\in[10^{-16},10^{-6}]M_{\odot}$.
