Description

In this talk, I will introduce the effective field theory (EFT) approach as a powerful tool for studying the dynamics of compact binary systems in scalar-tensor and Einstein-scalar-Gauss-Bonnet (ESGB) gravity. I will discuss state-of-the-art progress in deriving the conservative dynamics for both spinless and spinning binaries, emphasizing the efficiency of the EFT framework. These results provide important insights into deviations from General Relativity, offering testable predictions for gravitational wave observations and probing the validity of modified gravity theories.
