后闵可夫斯基可观测量的辐射程函

Radiation eikonal for post-Minkowskian observables

Jung-Wook Kim

AI总结:

本研究将辐射耗散效应纳入程函作为散射生成元的框架,通过引入媒介子场自由度提出辐射程函推广方案,并经散射波形等多个后闵可夫斯基散射可观测量验证有效。

摘要:

近期一项提议将程函重新诠释为散射生成元,通过将作用量作为对称生成元来计算散射可观测量。本研究旨在将辐射带来的耗散效应纳入该框架,通过引入媒介子场自由度将程函推广为辐射程函。该推广方案通过多个后闵可夫斯基散射可观测量进行了验证:散射波形、辐射动量,以及冲量中的(时间不对称)辐射损耗。

英文摘要:

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 generalised to the radiation eikonal by including mediator field degrees of freedom. The proposed generalisation is tested through several post-Minkowskian scattering observables; scattering waveform, radiated momentum, and (time asymmetric) radiation loss in the impulse.
