We propose that the dynamics of Kerr black holes is strongly constrained by the principle of gauge symmetry. We initiate the construction of effective field theories for Kerr black holes of any integer quantum spin s using Stückelberg fields, and show that the known three-point Kerr amplitudes are uniquely predicted using massive higher-spin gauge symmetry. This symmetry is argued to be connected to an enhanced range of validity for the Kerr effective field theories. We consider the closely related root-Kerr electromagnetic solution in parallel, for which the dynamical interactions with photons are also constrained by massive higher-spin gauge symmetry. Finally, the spin-s Compton amplitudes are analyzed, and we discuss contact-term constraints at s=2 from Ward identities.
我们提出，克尔黑洞的动力学受到规范对称性原理的强烈约束。我们利用施特克尔贝格场开始构建任意整数量子自旋s的克尔黑洞有效场论，并表明已知的三点克尔振幅是通过大质量高自旋规范对称性唯一预测出来的。这种对称性被认为与克尔有效场论有效性范围的扩大有关。我们同时考虑了与之密切相关的根克尔电磁解，其与光子的动力学相互作用也受到大质量高自旋规范对称性的约束。最后，对自旋-s康普顿振幅进行了分析，并从沃德恒等式讨论了s = 2时的接触项约束。
