标题： Conservative (failed)-tail effects at the fifth post-Newtonian order

摘要： 本文研究了保守动力学中紧致双星系统在5PN阶的尾部和“失效”尾部区域。我们采用Fokker-Lagrangian方法并结合维度正则化，发现尾部区域的结果与先前的EFT计算完全一致。至于“失效”尾部区域，我们有充分的理由相信，这一新的计算将有助于解决当前文献中的分歧。 显示英文摘要

摘要： This work deals with the tail and ``failed'' tail sectors of the conservative dynamics for compact binary systems at the 5PN order. We employ the Fokker Lagrangian method with dimensional regularization, and our results for the tail sector are perfectly consistent with the previous EFT computations. As for the ``failed'' tail sector, we have good hopes that this new computation will help solving the current discrepancy in the literature.
