Title: Magnusian: an integrated approach to gravitational dynamics

Abstract: One of key theoretical inputs for gravitational wave detection is an analytic description of binary dynamics, which provides the foundation for constructing waveform models used to generate waveform templates for detection. The conventional approach to binary dynamics is to construct the effective two-body Hamiltonian, which provides the equations of motion of the binary source. Motivated by the eikonal approximation of 2-to-2 scattering amplitudes in particle physics, we propose to approach the binary dynamics using the Magnusian (eikonal generator), which can be considered as integrated equations of motion. How the new approach relates to post-Minkowskian gravity, and the potential benefits that the new approach may provide, will be discussed.
