论文摘要
黑洞的超沉载已被用来将非常强的界限放在各种超轻玻色子的模型上，例如轴，新的轻鳞和深色光子。人们普遍认为，超级范围的界限广泛独立，因此非常健壮。然而，在这项工作中，我们表明，深色光子上的超级范围界限可能会受到最小模型的简单，引人入胜的扩展的挑战。特别是，如果深色光子在扮演暗物质角色的黑暗效果中填充了一个更大的黑暗区域，则可以轻松地绕过范围，具体取决于质量和（深色）暗物质的电荷。
Black-hole superradiance has been used to place very strong bounds on a variety of models of ultralight bosons such as axions, new light scalars, and dark photons. It is common lore to believe that superradiance bounds are broadly model independent and therefore pretty robust. In this work we show however that superradiance bounds on dark photons can be challenged by simple, compelling extensions of the minimal model. In particular, if the dark photon populates a larger dark sector and couples to dark fermions playing the role of dark matter, then superradiance bounds can easily be circumvented, depending on the mass and (dark) charge of the dark matter.
