Abstract: The detection of gravitational waves from merging black hole binaries triggered a search for an efficient theoretical description. One such approach is a field theoretical description of interacting Kerr black holes in terms of massive higher spin fields. In this talk, we shall give a brief introduction to some necessary ingredients of this approach, such as worldline description of Black Holes, spinor helicity formalism for scattering amplitudes and higher spin gauge theories. Then we shall show how to construct an action that reproduces the cubic interactions between Kerr Black Holes and Gravitational Waves.
