Article Synopsis
- The article presents a new gravitational Compton amplitude for rotating Kerr black holes applicable to any quantum spin, from zero to infinity.
- It utilizes concepts from higher-spin quantum field theory, such as gauge invariance, to derive classical amplitudes with respect to the spin vector.
- The study emphasizes using a chiral-field approach for clarity in degrees of freedom and simplifies interactions, allowing for comparisons with existing general-relativity results up to eighth order in spin.

Article Synopsis
- The dynamics of Kerr black holes are significantly influenced by gauge symmetry principles, leading to the development of effective field theories for these black holes based on integer quantum spins.
- Using Stückelberg fields, the research predicts known three-point Kerr amplitudes through the lens of massive higher-spin gauge symmetry, which may enhance the theories' applicability.
- The study also investigates the root-Kerr electromagnetic solution and examines the interactions with photons, focusing on spin-s Compton amplitudes and the implications of Ward identities for contact-term constraints at spin 2.
