论文摘要
我们在IIB字符串理论的压缩合奏中获得了黑洞超级的约束。约束只需要知道轴突质量和自我互动，并且对宇宙学模型不敏感。我们研究了超过$ 2 \ cdot 10^5 $ calabi-yau歧管，带有hodge数字$ 1 \ leq h^{1,1} \ leq 491 $，并在每个几何形状的模量空间中在两个参考空间中计算轴突光谱。我们对经典理论的计算是明确的，而对于插入式轴心电位，我们使用保守的模型。天体物理黑洞的测量特性不包括我们数据集的一部分。在模量空间与拉伸Kähler锥的尖端相对应的位置，我们在95％C.L.中排除了$ \ \ \％的流形，而在KählerCone内，在KählerCone内进一步，在一个极端的位置，以实现标准型号的极端点，我们将最高$ \ $ \ flaster的$ \ h^$ h^$ h^$ h^$ h^^}排除在外。 $ h^{1,1} = 100 $。
We obtain constraints from black hole superradiance in an ensemble of compactifications of type IIB string theory. The constraints require knowing only the axion masses and self-interactions, and are insensitive to the cosmological model. We study more than $2 \cdot 10^5$ Calabi-Yau manifolds with Hodge numbers $1\leq h^{1,1}\leq 491$ and compute the axion spectrum at two reference points in moduli space for each geometry. Our computation of the classical theory is explicit, while for the instanton-generated axion potential we use a conservative model. The measured properties of astrophysical black holes exclude parts of our dataset. At the point in moduli space corresponding to the tip of the stretched Kähler cone, we exclude $\approx 50\%$ of manifolds in our sample at 95% C.L., while further inside the Kähler cone, at an extremal point for realising the Standard Model, we exclude a maximum of $\approx 7\%$ of manifolds at $h^{1,1}=11$, falling to nearly zero by $h^{1,1}=100$.
