Description
High-accuracy theoretical predictions for the motion of compact binary systems are crucial for maximizing the discovery potential of current and future gravitational-wave observations, such as LIGO-Virgo-Kagra and LISA. The Effective Field Theory methodology, combined with modern multi-loop techniques, has proven to be exceptionally powerful for analytically solving the gravitational two-body inspiralling problem in post-Minkowskian approximation. This talk explore recent advancements in the worldline EFT and its application in computing two-body inspiralling dynamics, with a focus on the recently-obtained results at the fourth PM order (NNNLO).
