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…
Geodesics From Classical Double Copy
Riccardo Gonzo, Canxin Shi
We extend the Kerr-Schild double copy to the case of a probe particle moving in the Kerr-Schild background. In particular, we solve Wong's equations for a test color charge in a Co…
Asymptotic Charges and Coherent States in QCD
Riccardo Gonzo, Tristan McLoughlin, Diego Medrano +1
We study the connection between asymptotic symmetries in non-Abelian gauge theories and the generalised coherent states following from the application to QCD of the Faddeev-Kulish…
