论文摘要
由于直接检测实验中的WIMP无效，因此以银河系或宏观物体（Primordial黑洞（PBH）等宏观物体）的宏观颗粒或宏观对象成为有吸引力的DM候选物。我们探讨了当前PBHS作为生产光增强DM的新来源的可能性，并将Light PBH与当前和未来的陆地设施相关。我们研究电子弹性散射数据，并在PBH蒸发中从Super-Kamiokande和Xenon1t中获得当前的约束。子GEV DM - 电子散射横截面和由PBHS $ f _ {\ rm PBH} $组成的DM的比例也被施加在未来的Xenon实验中。
Light sub-GeV dark matter (DM) particles in the Milky Way or macroscopic objects such as primordial black holes (PBHs) become attractive DM candidates due to null results of WIMP from direct detection experiments. We explore the possibility in which the present PBHs play as a novel source to produce light boosted DM and confine light PBHs with current and future terrestrial facilities. We study the electron elastic scattering data and obtain the current constraints from Super-Kamiokande and XENON1T on the boosted DM from PBH evaporation. The prospective bounds on the sub-GeV DM-electron scattering cross section and the fraction of DM composed of PBHs $f_{\rm PBH}$ are also imposed for future Xenon experiments.
