Description
The application of quantum field theory methods to the relativistic two-body problem in gravity has led to extraordinary advances in recent years, with applications to real gravitational wave physics. I will demonstrate how the WQFT formalism leads to particularly interesting Feynman integrals that at 4 loops fit neatly into a hierarchy of increasing difficulty: 0SF, 1SF, and 2SF. I will review results on the first two orders and discuss additional challenges at 2SF.
