Black-hole scattering with general spin directions from minimal-coupling amplitudes
- Abstract:
- We study the link between classical scattering of spinning black holes and quantum amplitudes for massive spin- s particles. Generic spin orientations of the black holes are considered, allowing their spins to be deflected on par with their momenta. We rederive the spin-exponentiated structure of the relevant tree-level amplitude from minimal coupling to Einstein’s gravity, which in the s → ∞ limit generates the black holes’ complete series of spin-induced multipoles. The resulting scattering function is seen to encode in a simple way the known net changes in the black-hole momenta and spins at first post-Minkowskian order. We connect our findings to a rigorous framework developed elsewhere for computing such observables from amplitudes.
