论文摘要
我们通过明确求解发射颗粒的电磁粒子层层，并将这种发射能量的沉积到背景baryon-photon等血浆中来得出新的CMB各向异性功率谱和BBN约束，以蒸发原始黑洞。我们表明，与BBN和CMB光谱失真相比，CMB各向异性可以提供更强的限制因素，其质量小至$ M _ {\ rm bh} = 1.1 \ times 10^{13} $ G，比现在在文献中所考虑的质量略小。我们还表明，通过有关氘和氦3的丰富性的更多最新数据，BBN的约束得到了显着加强。
We derive new CMB anisotropy power spectrum and BBN constraints for evaporating primordial black holes by explicitly solving the electromagnetic particle cascades of emitted particles and the deposition of this emitted energy to the background baryon-photon plasma. We show that the CMB anisotropies can provide stronger constraints compared to BBN and CMB spectral distortions on black holes with masses as small as $M_{\rm BH}=1.1\times 10^{13}$g, a slightly smaller mass than what has been considered in literature until now. We also show that, with more up-to-date data on abundances of deuterium and helium-3, BBN constraints are strengthened significantly.
