论文摘要
从原始黑洞（PBH）注入鹰辐射的粒子的级联反应可以通过电离和加热呈乳层培养基来改变宇宙重组历史，从而改变宇宙微波背景（CMB）的各向异性光谱。在本文中，我们研究了几个未来的CMB实验的预期灵敏度，以限制$ 10^{15} \ sim10^{17} $ g质量窗口的PBHS的丰度，该质量是根据四个质量函数的：单色，对数正态，正态，强力法和关键崩溃模型。我们的结果表明，未来的实验（例如CMB-S4和PICO）可以将电流{\ it {planck}}界限提高约两个幅度。当前CMB数据允许的PBH参数空间中的所有区域，包括质量重的单色分布的PBH，超过$ 4 \ times 10^{16} $ grams，可以通过具有很高意义的任务来排除。
Cascade of particles injected as Hawking Radiation from Primordial Black Holes (PBH) can potentially change the cosmic recombination history by ionizing and heating the intergalactic medium, which results in altering the anisotropy spectra of the Cosmic Microwave Background (CMB). In this paper, we study the expected sensitivity of several future CMB experiments in constraining the abundance of PBHs distributed in $10^{15}\sim10^{17}$ g mass window according to four mass functions: the monochromatic, log-normal, power-law and critical collapse models. Our result shows that future experiments, such as CMB-S4 and PICO, can improve current {\it{Planck}} bounds by about two orders of magnitudes. All regions in PBH parameter space that are allowed by current CMB data, including monochromatically distributed PBHs with mass heavier than $4 \times 10^{16}$ grams, can be excluded by upcoming missions with high significance.
