论文摘要
通过使用增强机制在自然膨胀中使用具有峰值功能的增强机制，使用具有峰值功能的增强机制来生产原始黑洞（PBH）暗物质（DM）和标量引起的次级重力波。我们明确地表明，可以以$ 10^{12} $ MPC $^{ - 1} $，$ 10^{8} $ 10^{8} $ MPC $^{ - 1} $和$ 10^{5} $ 10^{5} $ mpc $^{ - 1} $通过调节模型参数来调整。借助增强的原始曲率扰动，我们显示了PBH DM的产生，峰值质量约为$ 10^{ - 13} \ M _ {\ odot} $，地球的质量和恒星质量，量表的产生，标量产生的引力（sigws），峰值频率（sigws），峰值频率为MHz，MHz，$ 10^^$ nousy $ 10^^^^$ nhim ake-6^$ nhh，H。具有质量尺度$ 10^{ - 13} \ m _ {\ odot} $的PBHs几乎可以构成所有DM，并且相关的SIGW可以通过基于间隔的重力波观测值来测试。
The production of primordial black hole (PBH) dark matter (DM) and the generation of scalar induced secondary gravitational waves by using the enhancement mechanism with a peak function in the non-canonical kinetic term in natural inflation is discussed. We show explicitly that the power spectrum for the primordial curvature perturbation can be enhanced at $10^{12}$ Mpc$^{-1}$, $10^{8}$ Mpc$^{-1}$ and $10^{5}$ Mpc$^{-1}$ by adjusting the model parameters. With the enhanced primordial curvature perturbations, we show the production of PBH DM with peak masses around $10^{-13}\ M_{\odot}$, the Earth's mass and the stellar mass, and the generation of scalar induced gravitational waves (SIGWs) with peak frequencies around mHz, $10^{-6}$ Hz and nHz, respectively. The PBHs with the mass scale $10^{-13}\ M_{\odot}$ can make up almost all the DM and the associated SIGWs is testable by spaced based gravitational wave observatory.
