论文摘要
旋转的黑洞（BHS）可以通过超沉淀有效地将能量传递到周围环境中。特别是，当粒子的康普顿长度与BH的重力半径相媲美时，粒子的职业数量可以成倍扩增。在这项工作中，我们研究了原始黑人洞（PBH）超级不稳定性对重型玻色粒暗物质（DM）产生的影响，质量高于$ \ sim $ 1 tev。此外，我们分析了其与其他纯粹的重力，因此不可避免的DM生产机制（例如霍金发射和紫外线冻结）的相互作用。我们发现，相对于仅考虑鹰发射的情况，超高可以显着增加PBH产生的DM密度，因此需要较低的初始PBH密度。
Rotating black holes (BHs) can efficiently transfer energy to the surrounding environment via superradiance. In particular, when the Compton length of a particle is comparable to the gravitational radius of a BH, the particle's occupation number can be exponentially amplified. In this work, we investigate the effect of the primordial-black-hole (PBH) superradiant instabilities on the generation of heavy bosonic dark matter (DM) with mass above $\sim$ 1 TeV. Additionally, we analyze its interplay with other purely gravitational and therefore unavoidable DM production mechanisms such as Hawking emission and the ultraviolet freeze-in. We find that superradiance can significantly increase the DM density produced by PBHs with respect to the case that only considers Hawking emission, and hence lower initial PBH densities are required.
