论文摘要
我们探讨了原始黑洞（PBHS）在今天含有电荷的可能性。我们发现，由于Horizon Crossing处的泊松波动或高能粒子碰撞，PBHS应在其形成中保持非零净电荷。尽管初始充电配置通过颗粒积聚或量子粒子发射进行快速放电过程，但我们表明，最大旋转的PBH可以产生能够保护它们免于放电的磁场。此外，鉴于电子是最轻，最快的电荷载体，我们表明病毒化的暗物质光环中的血浆可以赋予PBHS净负电荷。我们报告了$ 10^{ - 31} \，C/\ Mbox {kg} $和$ 10^{ - 15} \，C/\ Mbox {kg} $的$ 10^{ - 31} \，C/\ Mbox {kg} $之间的费用与质量比率。
We explore the possibility that primordial black holes (PBHs) contain electric charge down to the present day. We find that PBHs should hold a non-zero net charge at their formation, due to either Poisson fluctuations at horizon crossing or high-energy particle collisions. Although initial charge configurations are subject to fast discharge processes through particle accretion or quantum particle emission, we show that maximally rotating PBHs could produce magnetic fields able to shield them from discharge. Moreover, given that electrons are the lightest and fastest charge carriers, we show that the plasma within virialised dark matter haloes can endow PBHs with net negative charge. We report charge-to-mass ratios between $10^{-31}\,C/\mbox{kg}$ and $10^{-15}\,C/\mbox{kg}$ for PBHs within the mass windows that allow them to constitute the entirety of the dark matter in the Universe.
