Bethe-Salpeter equation for classical gravitational bound states

T Adamo, R Gonzo - Journal of High Energy Physics, 2023 - Springer
A bstract The Bethe-Salpeter equation is a non-perturbative, relativistic and covariant
description of two-body bound states. We derive the classical Bethe-Salpeter equation for …

Scattering of gravitational waves off spinning compact objects with an effective worldline theory

MVS Saketh, J Vines - Physical Review D, 2022 - APS
We study the process, within classical general relativity, in which an incident gravitational
plane wave, of weak amplitude and long wavelength, scatters off a massive spinning …
