论文摘要
我们通过同时从小，$ \ sillsim 10^6 $ kg，原始黑色的黑洞（pbhs）来研究重型，$ \ gtrsim 1 $ tev，bosonic spin $ s = 0,1 $暗物质（DM）。即使对于小初始PBH旋转，SR工艺也会产生极重的重力DM Bose或Proca Soliton Radius $ \ sillsim {\ rm pm} $和质量$ \ sim $ \ sim 10^{\ rm少数} $ kg，在PBH衰败后可以生存。这些孤子可以构成DM密度的很大一部分，在矢量DM情况下上升至$ \ gtrsim 50 \％$。
We study the production of heavy, $μ\gtrsim 1$ TeV, bosonic spin $s=0,1$ dark matter (DM) via the simultaneous processes of Hawking evaporation and superradiance (SR) from an initial population of small, $\lesssim 10^6$ kg, primordial black holes (PBHs). Even for small initial PBH spins the SR process can produce extremely dense gravitationally-bound DM Bose or Proca soliton "stars" of radius $\lesssim {\rm pm}$ and mass $\sim 10^{\rm few}$ kg that can survive to today, well after PBH decay. These solitons can constitute a significant fraction of the DM density, rising to $\gtrsim 50\%$ in the vector DM case.
