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 the weakly interacting massive particle 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 $f_{\mathrm{PBH}}$ are also imposed for future Xenon experiments.

原初黑洞蒸发产生的轻暗物质的电子靶实验约束

银河系中的轻亚 GeV 暗物质 (DM) 粒子或原始黑洞 (PBH) 等宏观物体成为有吸引力的 DM 候选者，因为直接探测实验中的弱相互作用大质量粒子的结果无效。我们探讨了将目前的 PBH 作为一种新型光源来产生光增强 DM 并将轻型 PBH 限制在当前和未来的地面设施中的可能性。我们研究了电子弹性散射数据，并获得了 Super-Kamiokande 和 XENON1T 对 PBH 蒸发增强 DM 的当前约束。亚GeV DM-电子散射截面的预期界限和由PBHs组成的DM比例$F_{\mathrm{PBH}}$也适用于未来的氙灯实验。
