| contents | We use Effective Field Theory techniques to derive the quadrupole-quadrupole part of the gravitational wave, obtaining a waveform in agreement with previous results found within the multipolar-post-Minkowskian method. In particular we emphasize the role of radiation-reaction terms, which affect the energy-momentum balance between source and radiation. An in-in effective action is then derived along the same principles and it is shown to provide energy and angular momentum balance equations in agreement with the corresponding fluxes carried at infinity by gravitational radiation. |
