Description
I will describe how using a Heavy-mass Effective Field Theory (HEFT) enables an efficient determination of the classical limit of observables in general relativity. Specifically, quantum-suppressed terms and hyper-classical corrections can be dropped from the get go, i.e. before any integrations. I will then discuss a significant application of the HEFT: the computation of the one-loop gravitational Bremsstrahlung and the associated scattering waveforms in the frequency and time domains. We will also see how HEFT amplitudes appear naturally in the KMOC approach to classical observables. Finally, I will conclude with some prospects for future work.
