摘要

最近的一项提议将eikonal重新解释为散射发生器，它通过一个动作作为对称发生器计算散射观测值。本研究的目的是将辐射的耗散效应纳入该框架，其中通过包括介质场自由度将eikonal普遍化。通过几个后闵可夫斯基散射观测值验证了所提出的推广；散射波形、辐射动量和脉冲中的（时间不对称）辐射损耗。2025年由美国物理学会出版

Radiation eikonal for post-Minkowskian observables

A recent proposal reinterprets the eikonal as the scattering generator, which computes scattering observables through an action as a symmetry generator. The aim of this study is to incorporate dissipative effects from radiation into this framework, where the eikonal is generalized to the by including mediator field degrees of freedom. The proposed generalization is tested through several post-Minkowskian scattering observables; scattering waveform, radiated momentum, and (time-asymmetric) radiation loss in the impulse.
