论文摘要
Feynman图在上下文中的一个分解特性最近采用了紧凑型二进制问题的有效现场理论方法,以有效地确定Newtonian(5pn)阶命令第五阶段潜力的静态部门。我们将此过程扩展到非静态图的情况,并通过基本代数操作来固定它,以5pn顺序以1000多个图的值来固定,这是完全确定动力学在5PN所需的图表的很大一部分。该过程解决了冗余问题,该问题困扰着结合能相对于更“有效”的可观察力(如散射角)的计算,从而使EFT接近谐波量表至少与其他方法一样可扩展。
A factorisation property of Feynman diagrams in the context the Effective Field Theory approach to the compact binary problem has been recently employed to efficiently determine the static sector of the potential at fifth post-Newtonian (5PN) order. We extend this procedure to the case of non-static diagrams and we use it to fix, by means of elementary algebraic manipulations, the value of more than one thousand diagrams at 5PN order, that is a substantial fraction of the diagrams needed to fully determine the dynamics at 5PN. This procedure addresses the redundancy problem that plagues the computation of the binding energy with respect to more "efficient" observables like the scattering angle, thus making the EFT approach in harmonic gauge at least as scalable as the others methods.
