Description
We calculated the conservative dynamics of binary systems in Einstein-Scalar-Gauss-Bonnet theory to the third Post-Minkowskian (PM) order using the worldline effective field theory (EFT) approach. By integrating out both the scalar and metric degrees of freedom, we obtained the impulse up to 3PM order, from which the scattering angles follow. We also computed the tidal effects within this framework. Furthermore, we cross-checked our results against the Post-Newtonian (PN) expansion, finding full agreement in the overlapping regime. Our results will help construct theory-dependent high-precision gravitational-wave waveform templates.
