我们更新了宇宙进入质量范围为10(9)-10(17)g的原始黑洞的限制条件，这些限制与它们的蒸发对大爆炸核合成和河外光子背景的影响有关。我们首次包括了黑洞夸克和胶子发射对这些约束的所有影响，并解释了最新的观测进展。然后我们讨论了这个质量范围内的其他约束，结果表明，除了10(13)-10(14)g的小范围外，这些约束都弱于核合成和光子本底限制，在那里宇宙微波背景各向异性的衰减占主导地位。最后，我们回顾了非蒸发原始黑洞的引力和天体物理效应，更新了更大质量范围1-10(50)g的约束条件。
We update the constraints on the fraction of the Universe going into primordial black holes in the mass range 10(9)-10(17) g associated with the effects of their evaporations on big bang nucleosynthesis and the extragalactic photon background. We include for the first time all the effects of quark and gluon emission by black holes on these constraints and account for the latest observational developments. We then discuss the other constraints in this mass range and show that these are weaker than the nucleosynthesis and photon background limits, apart from a small range 10(13)-10(14) g, where the damping of cosmic microwave background anisotropies dominates. Finally we review the gravitational and astrophysical effects of nonevaporating primordial black holes, updating constraints over the broader mass range 1-10(50) g.
