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…
Scattering amplitudes and electromagnetic horizons
Anton Ilderton, William Lindved
We consider the scattering of charged particles on particular electromagnetic fields which have properties analogous to gravitational horizons. Classically, particles become causal…
Wave scattering event shapes at high energies
Riccardo Gonzo, Anton Ilderton
We study the space and properties of global and local observables for radiation emitted in the scattering of a massive scalar field in gauge and gravitational plane-wave background…
Large Gauge Effects and the Structure of Amplitudes
Andrea Cristofoli, Asaad Elkhidir, Anton Ilderton +1
We show that large gauge transformations modify the structure of momentum conservation leading to non-vanishing three-point amplitudes in a simple toy model of a gravitational wave…
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…
Classical physics from amplitudes on curved backgrounds
Tim Adamo, Andrea Cristofoli, Anton Ilderton
We generalise the Kosower-Maybee-O'Connell (KMOC) formalism relating classical observables and scattering amplitudes to curved backgrounds. We show how to compute the final semicla…
