论文摘要
我们在Wess-Zumino类型的无尺度超级重力模型的背景下计算原始黑洞的丰度。我们通过添加额外的指数术语来修改Kähler的潜力。在此模型的上下文中,我们只使用一个参数,我们能够满足光谱索引$ n_s $,张量与刻录比率$ r $ $ r $的Planck宇宙学约束,并以原始黑洞的形式产生了宇宙暗物质的$ \ sim 20 \%20 \%$。
We calculate the primordial black hole abundance in the context of a Wess-Zumino type no-scale supergravity model. We modify the Kähler potential, by adding an extra exponential term. Using just one parameter in the context of this model, we are able to satisfy the Planck cosmological constraints for the spectral index $n_s$, the tensor-to-scalar ratio $r$, and to produce up to $\sim 20\%$ of the dark matter of the Universe in the form of primordial black holes.
