Weekly QG group meeting.
Speaker: Mirian Tsulaia.
Title: "Cubic Action for Spinning Black Holes".

We discuss an effective field theoretic approach to description of scattering of two Kerr Black Holes, emitting gravitational waves. In this approach one considers massive higher spin fields interacting with gravitational and electromagnetic fields. We use a BRST formalism, similar to the Open String Field Theory, to construct a cubic action for two massive higher spin fields and one massless spin two (or spin one) field. This action reproduces the cubic amplitudes that correspond to the interactions between Kerr Black Holes.
