论文摘要

如果在通货膨胀的小尺度上产生大型扰动,则可以形成原始的黑洞(PBH)。我们研究了具有当地最低限度的玩具通货膨胀模型。当充气通过局部最小值时,曲率扰动会增强,并且比准发出点膨胀的效率更高,从而导致PBH在小尺度上产生。 PBHS​​可以包含质量窗口中的总暗物质$ 10^{16} $ - $ 10^{20} $ g。

Primordial black holes (PBHs) could be formed if large perturbations are generated on small scales in inflation. We study a toy inflation model with a local minimum. The curvature perturbations are enhanced when the inflaton passes through the local minimum, with more efficient amplification rate than that of quasi-inflection point inflation, leading to the production of PBHs on small scales. The PBHs could comprise the total dark matter in the mass window $10^{16}$--$10^{20}$g.
