-Forms on the Celestial Sphere
Laura Donnay, Erfan Esmaeili, Carlo Heissenberg
We construct a basis of conformal primary wavefunctions (CPWs) for -form fields in any dimension, calculating their scalar products and exhibiting the change of basis between co…
Classical Gravitational Observables from the Eikonal Operator
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo +1
We propose two possible eikonal operators encoding the effects of classical radiation as coherent states of gravitons and show how to compute from them different classical observab…
Angular Momentum Loss Due to Tidal Effects in the Post-Minkowskian Expansion
Carlo Heissenberg
We calculate the tidal corrections to the loss of angular momentum in a two-body collision at leading Post-Minkowskian order from an amplitude-based approach. The eikonal operator…
The eikonal operator at arbitrary velocities I: the soft-radiation limit
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo +1
Observables related to the real part of the gravitational eikonal, such as the deflection angle and time delay, have been found so far to have a smooth post-Minkowskian (PM) expans…
Angular momentum of zero-frequency gravitons
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo
By following closely Weinberg's soft theorem, which captures the pole contribution to the amplitude for soft graviton emissions () on top of an arbitrary background hard…
