报告摘要：

In this talk, we will discuss the scattering of scalar waves off compact objects, such as neutron stars or black holes, using the worldline effective field theory (EFT). By employing modern techniques of scattering amplitudes, we have managed to calculate the third post-Minkowskian (PM) order (i.e., two-loop) for the scattering phase shift. This calculation reveals the classical running of the dynamical Love number. Furthermore, by considering the scattering off black holes, we have precisely matched our phase shift to the results from black hole perturbation theory in general relativity. This confirms that the relevant static Love number is indeed zero, and also allows for extracting the classically running.
