We study the effect of the scotogenic dark matter on the primordial black holes (PBHs) and vice versa. We show that if the PBHs evaporate in the radiation dominated era, the upper limit of the initial mass of the PBHs Min should be constrained as 104 M in/MPl 1010 for 𝒪(1) TeV scotogenic dark matter (𝒪(1) TeV is the most appropriate energy scale in the scotogenic model). On the other hand, if the PBHs evaporate in the PBH dominated era, a quite heavy scotogenic dark matter (mDM 109 GeV) for Min/MPl 1013 may be allowed.

原始黑洞和暗物质

我们研究了暗物质对原始黑洞 (PBH) 的影响,反之亦然。我们表明,如果 PBHs 在辐射主导时代蒸发,则 PBHs 初始质量的上限应限制为104 /PL 1010为了𝒪(1)TeV 暗物质(𝒪(1)TeV 是 scotogenic 模型中最合适的能量尺度)。另一方面,如果 PBHs 在 PBH 占主导地位的时代蒸发,一种相当重的暗物质(DM 109GeV) 为/PL 1013可能被允许。
