Five-dimensional Geometry from Spinning Amplitudes
Lucile Cangemi, Iustin Surubaru
Massive spinor-helicity variables in four dimensions are a useful tool for studying amplitudes between higher-spin fields and gravitons. Among them a special, simple set of amplitu…

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…

Binary Kerr black-hole scattering at 2PM from quantum higher-spin Compton
Lara Bohnenblust, Lucile Cangemi, Henrik Johansson +1
Quantum higher-spin theory applied to Compton amplitudes has proven to be surprisingly useful for elucidating Kerr black hole dynamics. Here we apply the framework to compute scatt…
