On two body gravitational scattering within perturbative gravit
arXiv:2304.08812 · doi:10.1088/1361-6382/ad0b38
Abstract
We discuss an alternative approach to studying the low energy limit of quantum general relativity. We investigate the low energy limit of a scattering cross-section for two massive scalar particles. Unlike calculations involving the reconstruction of the gravitational potential, our approach avoids ambiguities and is applicable in any frame. Our results are in agreement with both relativistic and non-relativistic calculations. The non-analytic parts of scattering amplitudes that are dominant in the low energy limit also contribute to the cross-section and provide a way to separate the lading order corrections.
