| contents | Using the worldline quantum field theory approach we derive solutions to the equations of motion for spinning massive bodies up to quadratic order in spins. At leading post-Minkowskian (PM) order these trajectories are obtained in the time domain, and at sub-leading order in the frequency domain. Our approach incorporates diagrammatic techniques and modern Feynman integration technologies, and includes a new family of loop integrals different to those seen in asymptotic PM calculations. Our results provide a new mechanism for computing the radiated angular momentum involved in gravitational scattering, which we reproduce at 2PM order up to linear spins. We have established a framework for computing higher-order effects to further extend the high-precision frontier in analytical gravitational wave physics, and push predictions for the radiated angular momentum to higher perturbative orders. |
