HET Brown Bag | Binary Black Holes and Scattering Amplitudes
Mikhail Solon (Caltech)
We develop a systematic framework for describing binary dynamics using modern tools from quantum field theory. Our approach combines onshell methods such as generalized unitarity and the double-copy construction with effective field theory methods for integration and matching. As a first application, we derive a new result in general relativity: the third post-Minkowskian correction to the conservative two-body Hamiltonian for spinless black holes. Prospects and challenges for applying quantum field theory for the gravitational wave physics program are discussed.
