论文摘要
原始黑洞是暗物质的可能组成部分,研究它们的最有前途的方法是通过其鹰式蒸发的产物。由于此过程,发出的任何物种都比鹰温度较轻,包括超出标准模型以外的新粒子。然后可以通过与标准模型颗粒的相互作用在基于实验室的实验中检测到这些。在以前的工作中,我们首先提出并研究了这种情况,在光新物种与核子之间存在相互作用的情况下。在这里,我们扩展了此讨论,以包括与电子相互作用的情况。我们表明,与$ 100 $ 100 $ MEV的原始黑洞和物种同时存在受到直接检测实验的测量,例如Xenon1t和Water Cherenkov Neutrino探测器,例如Super-Kamiokande。我们的结果为宇宙学和对撞机的搜索提供了一种补充和替代的研究方式。
Primordial black holes are a possible component of dark matter, and a most promising way of investigating them is through the product of their Hawking evaporation. As a result of this process, any species lighter than the Hawking temperature is emitted, including possible new particles beyond the Standard Model. These can then be detected in lab-based experiments via their interaction with the Standard Model particles. In a previous work, we have first proposed and studied this scenario in the presence of an interaction between the light new species and nucleons. Here we extend this discussion to include the case of interaction with electrons. We show that the simultaneous presence of primordial black holes and species lighter than about $100$ MeV can be constrained by the measurements of direct detection experiments, such as XENON1T, and water Cherenkov neutrino detectors, such as Super-Kamiokande. Our results provide a complementary and alternative way of investigation with respect to cosmological and collider searches.
