Kerr worldline-QFT action from Compton amplitude to infinite spin orders
Maor Ben-Shahar, Lucile Cangemi, Henrik Johansson
We develop a quadratic-in-Riemann worldline action for a Kerr black hole at infinite spin orders by matching to a proposed tree-level Kerr Compton amplitude, originally obtained fr…

One-loop Amplitudes for N=2 Homogeneous Supergravities
Maor Ben-Shahar, Marco Chiodaroli
We compute one-loop matter amplitudes in homogeneous Maxwell-Einstein supergravities with N=2 supersymmetry using the double-copy construction. We start from amplitudes of N=2 supe…
