Leading soft theorems on plane wave backgrounds
Sonja Klisch
The infrared singularities of scattering amplitudes have historically contributed to much development in understanding fundamental structures in physics. However, the fate of the l…
Memory and supertranslations on plane wave spacetimes: an on-shell perspective
Andrea Cristofoli, Sonja Klisch
We revisit the computation of the classical gravitational waveform for a particle moving in a plane wave background using on-shell amplitudes. We emphasize the relationship between…
The KLT kernel in twistor space
Tim Adamo, Sonja Klisch
The double copy relationship between Yang-Mills theory and general relativity can be stated in terms of a field theory Kawai-Lewellen-Tye (KLT) momentum kernel, which maps two colo…
Scattering amplitudes for self-force
Tim Adamo, Andrea Cristofoli, Anton Ilderton +1
The self-force expansion allows the study of deviations from geodesic motion due to the emission of radiation and its consequent back-reaction. We investigate this scheme within th…
All order gravitational waveforms from scattering amplitudes
Tim Adamo, Andrea Cristofoli, Anton Ilderton +1
Waveforms are classical observables associated with any radiative physical process. Using scattering amplitudes, these are usually computed in a weak-field regime to some finite or…
