论文摘要
我们引入了一个新型框架,以研究其发射引力辐射的散射对二元的高阶重力影响。在这里,由于二进制重力电位的背景,我们关注辐射反应,即所谓的尾部效应,作为这种散射效应的起点。我们从二元复合粒子的有效场理论开始。通过多环和通用非军事方法,由于这些影响,我们得出了动态多物,能量光谱和可观察到的通量的因果有效作用。我们在第三次辐射反应效应中进行,在牛顿后重力的四环水平和第七阶,对高阶效应散发出新的灯光,并推动了最新的状态。
We introduce a novel framework to study high-order gravitational effects on a binary from the scattering of its emitted gravitational radiation. Here we focus on the radiation-reaction due to the background of the binary's gravitational potential, namely on the so-called tail effects, as the starting point to this type of scattering effects. We start from the effective field theory of a binary composite-particle. Through multi-loop and generalized-unitarity methods, we derive the causal effective actions of the dynamical multipoles, the energy spectra, and the observable flux, due to these effects. We proceed through the third subleading such radiation-reaction effect, at the four-loop level and seventh order in post-Newtonian gravity, shedding new light on the higher-order effects, and pushing the state of the art.
