摘要：

在早期宇宙中形成的原始黑洞（PBH）是通过霍金辐射发射中微子的来源。这样的天体物理中微子可以在地球上检测到，对彗星质量的PBH丰度的限制可以从中微子通量的零观测中得出。在这里，我们考虑非旋转PBH和改进的约束，使用超级神冈中微子数据，以及我们进行预测的下一代中微子（超神冈，JUNO，DUNE）和暗物质（DARWIN，ARGO）探测器，我们比较。对于质量小于$\sim \textrm{few} \times 10^{14}$ g的PBH，PBH现在应该已经蒸发了，而质量更大的PBH仍然存在，并构成宇宙暗物质的一部分。我们考虑单色和扩展（对数正态）的质量分布，和PBH质量范围从$10^{12}$ g到$\sim 10^{16}$ g。最后，我们还比较了我们的结果与以前的文献。

英文摘要：

Primordial black holes (PBHs) formed in the early Universe are sources of neutrinos emitted via Hawking radiation. Such astrophysical neutrinos could be detected at Earth and constraints on the abundance of comet-mass PBHs could be derived from the null observation of this neutrino flux. Here, we consider non-rotating PBHs and improve constraints using Super-Kamiokande neutrino data, as well as we perform forecasts for next-generation neutrino (Hyper-Kamiokande, JUNO, DUNE) and dark matter (DARWIN, ARGO) detectors, which we compare. For PBHs less massive than $\sim \textrm{few} \times 10^{14}$ g, PBHs would have already evaporated by now, whereas more massive PBHs would still be present and would constitute a fraction of the dark matter of the Universe. We consider monochromatic and extended (log-normal) mass distributions, and a PBH mass range spanning from $10^{12}$ g to $\sim 10^{16}$ g. Finally, we also compare our results with previous ones in the literature.
