报告摘要：
In this talk, I will briefly review the worldline effective field theory (EFT) formalism for classical gravitational physics. Using worldline EFT, I will provide a framework for understanding the gravitational analogue of Raman scattering, which describes wave scattering through compact stars, incorporating both tidal effects and dissipation. The EFT calculation of gravitational Raman scattering can be matched to black hole perturbation theory (BHPT) to extract information about Love numbers. We will also show the classical RG running of tidal operators. Furthermore, we interpret the result of this RG flow as the anomalous dimension of multipole operators, which are essentially the "renormalized angular momentum" in BHPT, determined by the far-zone phase shift. I will demonstrate how this anomalous dimension resums certain tail effects in the waveform. Finally, I will comment on how the worldline EFT might be useful in formal theory.
