我们证明了球对称带电黑洞事件视界外可能的模空间偏移的精确界限。在黑洞电荷\(Q (\phi)\)不小于其渐近值的区域，我们证明总模空间偏移小于\(\frac{\pi}{2\sqrt{k_N}}\)，其中\(k_N\)是有理化牛顿常数。我们还表明，在\(Q (\phi)\)非递减的特定方向上的模空间偏移满足相同界限。将我们的界限应用于带电黑洞，我们排除了微扰玻色弦理论中弱引力猜想最近一个证明[arXiv:2401.14449]中的一个潜在漏洞。
英文摘要
We prove sharp bounds on the moduli space excursion that is possible outside the event horizon of a spherically symmetric charged black hole. In regions where the black hole charge $Q (ϕ)$ is no less than its asymptotic value, we prove that the total moduli space excursion is less than $\fracπ{2\sqrt{k_N}}$ where $k_N$ is the rationalized Newton constant. We also show that the moduli space excursion in a specified direction in which $Q (ϕ)$ is non-decreasing satisfies the same bound. Applying our bound to electrically charged black holes, we rule out a potential loophole in a recent proof [arXiv:2401.14449] of the Weak Gravity Conjecture in perturbative bosonic string theory.
