Supertranslations are Soft Dressings
Asaad Elkhidir, Donal O'Connell, Radu Roiban
Asymptotic states of massive particles in electrodynamics and gravity are not uniquely defined because of the absence of a mass gap. Working in the KMOC formalism, we study the cla…
The ABCs of Amplitudes, Bogoliubov and Crossing
Rafael Aoude, Asaad Elkhidir, Anton Ilderton +2
It is now common to describe classical backgrounds involving dynamical black holes with the production of gravitational radiation using the methods of scattering amplitudes. In tha…
Hawking Radiation meets the Double Copy
Rafael Aoude, Donal O'Connell, Matteo Sergola +1
We describe an electromagnetic system which is related to black hole production with Hawking radiation through the double copy. We consider the scattering of a massless scalar part…
Amplitudes for Hawking Radiation
Rafael Aoude, Donal O'Connell, Matteo Sergola
We obtain the Hawking spectrum by exponentiating a series of Feynman diagrams describing a scalar field scattering through a collapse background. Our approach is rooted in semiclas…
Supertranslations from Scattering Amplitudes
Asaad Elkhidir, Donal O'Connell, Radu Roiban
On-shell methods have found a new application to local observables such as asymptotic radiation fields and gravitational waveforms. While these observables are invariant under smal…
Observables from the Spinning Eikonal
Andres Luna, Nathan Moynihan, Donal O'Connell +1
We study the classical dynamics of spinning particles using scattering amplitudes and eikonal exponentiation. We show that observables are determined by a simple algorithm. A wealt…
