Dirac brackets for classical radiative observables
Francesco Alessio, Riccardo Gonzo, Canxin Shi
We introduce a new coherent state expansion of the exponential representation of the S-matrix for the classical gravitational two-body problem. By combining the Kosower-Maybee-O'Co…

Scattering and bound observables for spinning particles in Kerr spacetime with generic spin orientations
Riccardo Gonzo, Canxin Shi
We derive the radial action of a spinning probe particle in Kerr spacetime from the worldline formalism in the first-order form, focusing on linear in spin effects. We then develop…

Boundary to bound dictionary for generic Kerr orbits
Riccardo Gonzo, Canxin Shi
We establish a new relation between classical observables for scattering and bound orbits of a massive probe particle in a Kerr background. We find an exact representation of the H…
