Gleaning gravitational amplitudes -- a double copy for canceling dilatons
Henrik Johansson, Ingrid Vazquez-Holm
Scattering amplitudes in general relativity can be conveniently computed using the double copy, which relates them to Yang-Mills amplitudes. However, unwanted dilatons are sourced…

From higher-spin gauge interactions to Compton amplitudes for root-Kerr
Lucile Cangemi, Marco Chiodaroli, Henrik Johansson +3
We develop massive higher-spin theory as a framework for describing dynamics of rotating compact objects, such as Kerr black holes. In this paper, we explore gauge interactions up…
