论文摘要
通过具有峰值的非规范动力学项提供的增强机制，可以通过七个数量级在小尺度上增强原始曲率扰动的幅度，同时保持与大尺度上的观察结果一致。在该机制中，峰功能和通货膨胀潜力不受限制。我们使用HIGGS模型和T模型作为示例，以说明如何产生具有不同质量和标量诱导的次级重力波的丰富原始黑孔暗物质具有不同的峰值频率。我们还表明，原始曲率扰动的增强功率光谱以及标量诱导的次级重力波的能量密度可以具有尖峰或宽峰。质量约为$ 10^{ - 14} -10^{ - 12} m _ {\ odot} $带有增强机制的原始黑孔，几乎可以构成所有暗物质，并且标量引起的继发性引力波伴随着原始黑洞的产生，可以用Pulsar的定时段落和分散的ward狂潮来证实。因此，可以通过原始黑洞暗物质和引力波观测来测试该机制。
With the enhancement mechanism provided by a noncanonical kinetic term with a peak, the amplitude of primordial curvature perturbations can be enhanced by seven orders of magnitude at small scales while keeping to be consistent with observations at large scales. The peak function and inflationary potential are not restricted in this mechanism. We use the Higgs model and T-model as examples to show how abundant primordial black hole dark matter with different mass and scalar induced secondary gravitational waves with different peak frequency are generated. We also show that the enhanced power spectrum for the primordial curvature perturbations and the energy density of the scalar induced secondary gravitational waves can have either a sharp peak or a broad peak. The primordial black holes with the mass around $10^{-14}-10^{-12} M_{\odot}$ produced with the enhancement mechanism can make up almost all dark matter, and the scalar induced secondary gravitational waves accompanied with the production of primordial black holes can be tested by the pulsar timing arrays and spaced based gravitational wave observatory. Therefore, the mechanism can be tested by primordial black hole dark matter and gravitational wave observations.
