Leveraging scattering information to describe binary systems in generic orbits requires identifying local- and nonlocal-in-time tail effects. We report here the derivation of the universal (non-spinning) local-in-time conservative dynamics at fourth Post-Minkowskian order, i.e. ${\cal O}(G^4)$. This is achieved by computing the nonlocal-in-time contribution to the deflection angle, and removing it from the full conservative value in [2112.11296,2210.05541]. Unlike the total result, the integration problem involves two scales, velocity and mass ratio, and features multiple polylogarithms, complete elliptic and iterated elliptic integrals, notably in the mass ratio. We reconstruct the local radial action, center-of-mass momentum and Hamiltonian, as well as the exact logarithmic-dependent part(s), all valid for generic orbits. We incorporate the remaining nonlocal terms for elliptic-like motion to sixth Post-Newtonian order. The combined Hamiltonian is in perfect agreement in the overlap with the Post-Newtonian state of the art. The results presented here provide the most accurate description of gravitationally-bound binaries harnessing scattering data to date, readily applicable to waveform modelling.

Conservative dynamics of two-body systems at the fourth post-Newtonian approximation of general relativity
第四后牛顿(4PN)两体动力学最近已经被几种不同的方法处理:有效场论,Arnowitt-Deser-Misner哈密顿量,作用角-Delaunay平均,有效单体,引力自力,动力学第一定律和Fokker作用量。我们回顾这些方法的成就,并讨论其结果的互补性。我们的主要结论是:(i)4PN动力学的第一次完整推导的结果[T.Damour,P.Jaranowski,and G.Schäfer,Phys. Rev. D 89,064058(2014)]已经被几个后续工作分段地完全证实;(ii)德劳内平均技术的结果[T.Damour,P.Jaranowski和G.Schäfer,Phys. Rev. D 91,084024(2015)]已被几项独立工作证实;以及(iii)最近Fokker作用计算中的几个主张[L.Bernard et al.,arXiv:1512.02876v2 [gr-qc]]是不正确的,但可以通过添加与红外和紫外发散正则化中的微妙之处相关的两个模糊参数来校正。

我们完成了分析测定,在第四后牛顿(4PN)近似下,引力相互作用的两点质量系统的保守动力学。通过考虑由于很久以前发现的无限范围尾传输时间相关性而导致的通常近区扩展的4PN分解[L.Blanchet和T.Damour,Phys. Rev. D 37,081503(R)(2013)],解决了阻碍了先前4PN计算的红外模糊性,从而获得了该完成。1410(1988)]。这导致了两个质量的庞加莱不变4PN精确有效作用量,它混合了瞬时相互作用项(由通常的哈密顿量描述)和(时间对称的)非定域的时间相互作用。
