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}(…
