论文摘要
我们认为候选光候选人源自Schwarzschild原始黑洞的蒸发，质量为$ 10^{ - 5} -10^9 $ g。这些候选者超出了标准模型粒子，与其他颗粒具有可忽略不计的耦合，因此它们仅在重力上相互作用。属于温暖的暗物质类别，它们仍然是变质结构的形成，对候选旋转值的增加具有更柔和的影响。要求此类候选人充分说明观察到的暗物质，我们发现，对于所有旋转值的旋转值排除了黑洞统治的场景。对于辐射统治的情况，我们得出了参数$β$的上限（原始黑洞的形成射击时，辐射效率较小），较小的是候选旋转。
We consider light dark matter candidates originated from the evaporation of Schwarzschild primordial black holes, with masses in the range $10^{-5}-10^9$ g. These candidates are beyond Standard Model particles with negligible couplings to the other particles, so that they interact only gravitationally. Belonging to the category of warm dark matter, they nevertheless spoil structure formation, with a softer impact for increasing values of the candidate spin. Requiring such candidates to fully account for the observed dark matter, we find that the scenario of black hole domination is ruled out for all spin values up to 2. For the scenario of radiation domination, we derive upper limits on the parameter $β$ (the primordial black hole energy density at formation over the radiation one), which are less stringent the higher the candidate spin is.
