在蒸发的最后阶段，一个位于附近的原始黑洞可以在伽马射线和中微子望远镜中产生可探测到的信号。我们重新评估了来自这些瞬变点事件的预期伽马射线和中微子通量，并讨论了现有约束的后果。对于伽马射线，我们将当前的界限改进了几倍，而对于中微子，我们得到了与现有文献显著不同的结果。深入讨论了中微子望远镜在寻找原始黑洞方面的能力和优势。伽马射线和中微子能量与时间分布的关联将被推广为在探测到原始黑洞的情况下识别原始黑洞的有力工具。
A primordial black hole in the last stages of evaporation and located in the local neighborhood can produce a detectable signal in gamma ray and neutrino telescopes. We re-evaluate the expected gamma ray and neutrino fluxes from these transient point events and discuss the consequences for existing constraints. For gamma rays we improve the current bounds by a factor of few, while for neutrinos we obtain significantly different results than the existing literature. The capability and advantages of neutrino telescopes in the search for primordial black holes is discussed thoroughly. The correlations of gamma ray and neutrino energy and time profiles will be promoted as a powerful tool in identifying the primordial black holes, in case of detection.
