Description
The Worldline Quantum Field Theory (WQFT) formalism has proven itself a powerful tool for perturbatively calculating the physical observables involved in two-body gravitational scattering events — change in momentum, scattering angles, radiated energy and angular momentum. In this talk I will review the WQFT formalism and summarise this progress. In particular, I will discuss recent work on scattering spinning black holes using bosonic worldline oscillators, and our recent state-of-the-art calculation of 5PM (4-loop) scattering observables, which includes functions deriving from a Calabi-Yau threefold geometry.
