Description
I will discuss the role of gauge symmetry for constraining Kerr dynamics. EFTs for both Kerr black holes and the closely related electromagnetic root-Kerr solution are considered using Stückelberg fields. This uniquely predicts the known Kerr three-point amplitudes to all spin using Ward identities that follow from massive gauge symmetry. I will also discuss aspects relevant to the analysis of the spin-s Compton amplitude and provide some explicit all-spin results for the non-Abelian root-Kerr Compton amplitude.
