SUMMARY:Lecture / Discussion:HET Brown Bag Seminar | Love number matching: uncovering the simplest EFT
DESCRIPTION:At wavelengths large compared to the source size\, any compact object admits a point-particle EFT whose finite-size effects are encoded by Love numbers. In this talk I will discuss a novel method to compute gravitational wave amplitudes by reinterpreting the Feynman diagram expansion as a Born series\, solution of an effective wave equation. This method enables efficient\, systematic calculations of scattering amplitudes off any compact object\, yielding new predictions for scalar black-hole Love numbers and their renormalization-group equations up to O(G^7).
