Description
Spin effects for Kerr black holes can be included systematically in field-theoretic calculations of the two-body problem. I will discuss one approach to incorporate spin which uses the synergy between on-shell scattering amplitudes and heavy particle effective theory (HPET). This framework is tailored to extract the classical parts of the computation and it exposes structure in the spin-multipole expansion. Some results from this approach include recent calculations to all orders in the spins of the black holes.
