Classical Spin Transitions and Absorptive Scattering
Juan Pablo Gatica, Callum R. T. Jones
We describe an on-shell, amplitudes-based approach to incorporating radiation absorption effects in the post-Minkowskian scattering of generic, compact, spinning bodies. Classical…
One-Loop Observables to Higher Order in Spin
Juan Pablo Gatica
We study observables in the scattering of classical, spinning objects using the KMOC formalism. In particular, we derive formulas to higher order in spin and one loop $\mathcal{O}(…
The Eikonal Phase and Spinning Observables
Juan Pablo Gatica
We set up the Kosower, Maybee, O'Connell formalism for generic spin following a previous field theory construction and use it to extract a next-to-leading order eikonal formula for…
Scalar QED as a toy model for higher-order effects in classical gravitational scattering
Zvi Bern, Juan Pablo Gatica, Enrico Herrmann +2
Quantum Electrodynamics (QED) serves as a useful toy model for classical observables in gravitational two-body systems with reduced complexity due to the linearity of QED. We inves…
