论文摘要
足够轻的原始黑洞（PBH）可以在很早的宇宙中蒸发，并稀释稳定文物的先前存在的Baryon不对称和/或冷冻密度。在PBHS衰减时以及何时主导宇宙学能量密度时，这种效果尤其强。首先，在PBH的Delta功能质谱和即时衰减近似中的简化假设下，首先通过分析进行分析计算。在指数衰减的现实情况下，对于PBH的扩展质谱，计算是数值的。导致超对称遗物的冷冻数密度降低为它们打开了一个更宽的窗口，成为可行的暗物质候选者。
Sufficiently light primordial black holes (PBH) could evaporate in the very early universe and dilute the preexisting baryon asymmetry and/or the frozen density of stable relics. The effect is especially strong in the case that PBHs decayed if and when they dominated the cosmological energy density. The size of the reduction is first calculated analytically under the simplifying assumption of the delta-function mass spectrum of PBH and in instant decay approximation. In the realistic case of exponential decay and for an extended mass spectrum of PBH the calculations are made numerically. Resulting reduction of the frozen number density of the supersymmetric relics opens for them a wider window to become viable dark matter candidate.
