论文摘要
我们研究了由原始黑孔（PBH）和自湿wimps（弱相互作用的巨粒子）组成的混合暗物质情景中的同步加速器发射。 wimps可以在PBHS周围形成超级型Minihalos，而这些致密光晕的歼灭增强可以导致在射频磁场存在下在射频下在射频下的有效同步辐射。 PBH分数相对于总暗物质的上限为$ 10^{ - 8} \ sim 10^{ - 5} $，具体取决于electroweak scale take wimp质量（$m_χ= 10 \ sim 1000 $ gev）和wimp nihihilation频道（例如，hadronic $χ\ tem b b \ b \ b \ b \ l b \ lep { $χχ\ rightarrow e^+ e^ - $ channel）。因此，当暗物质的另一个组成部分由常规的电子船秤组成时，PBH对总暗物质丰度的贡献可以忽略不计。
We study the synchrotron radio emission in the mixed dark matter scenarios consisting of the primordial black holes (PBHs) and the self-annihilating WIMPs (weakly interacting massive particles). The WIMPs can form the ultracompact minihalos around PBHs and the annihilation enhancement from these dense halos can lead to the efficient synchrotron radiation at the radio frequency in the presence of galactic magnetic fields. The upper bound of PBH fraction with respect to the total dark matter abundance is of order $10^{-8}\sim 10^{-5}$ depending on the electroweak scale WIMP mass ($m_χ=10\sim 1000$ GeV) and the WIMP annihilation channel (e.g. a hadronic $χχ\rightarrow b \bar{b}$ or a leptonic $χχ\rightarrow e^+ e^-$ channel). The PBH contribution to the total dark matter abundance is hence negligible when the other component of dark matter is composed of the conventional electroweak scale WIMPs.
