原始黑洞（PBH）可能在早期宇宙中占主导地位，并且在大爆炸核合成之前蒸发，可以为暗物质（DM）的产生机制提供新的冻结。所提出的方案被认为是两种可能的机制PBH的形成和相应的连续PBH质谱，使非单一PBH质谱的影响被考虑在PBH蒸发的结果，PBH主导在早期宇宙结束。我们指定的条件下，所提出的方案可以解释生产的暗物质在非常早期的宇宙。
Primordial Black Holes (PBH) could dominate in the early universe and, evaporating before Big bang Nucleosynthesis, can provide new freeze in mechanism of dark matter (DM) production. The proposed scenario is considered for two possible mechanisms of PBH formation and the corresponding continuous PBH mass spectra so that the effect of non-single PBH mass spectrum is taken into account in the results of PBH evaporation, by which PBH dominance in the early universe ends. We specify the conditions under which the proposed scenario can explain production of dark matter in very early Universe.
