双重副本涉及规范和引力理论中的散射振幅。在本文中，我们扩大了双拷贝的范围，通过系统的微扰展开来构造时空度规。微扰过程是基于杨-米尔斯理论中的直接计算，然后根据双拷贝算法对某些微扰图的分子进行平方。从这个过程的观点来看，最简单的球对称静止时空是詹尼斯-纽曼-维尼库尔裸奇点族的一个特殊成员。我们的工作为双副本应用于物理上有趣的问题（例如微扰黑洞散射）铺平了道路。
The double copy relates scattering amplitudes in gauge and gravity theories. In this paper, we expand the scope of the double copy to construct spacetime metrics through a systematic perturbative expansion. The perturbative procedure is based on direct calculation in Yang-Mills theory, followed by squaring the numerator of certain perturbative diagrams as specified by the double-copy algorithm. The simplest spherically symmetric, stationary spacetime from the point of view of this procedure is a particular member of the Janis-Newman-Winicour family of naked singularities. Our work paves the way for applications of the double copy to physically interesting problems such as perturbative black-hole scattering.
