论文摘要
我们使用两种Yang-Mills理论的BRST卷积产物，与Bern-Carrasco-Johansson（BCJ）双拷贝一起使用BRST卷积产物，构建纯重力Becchi-Rouet-stora-tyutin（BRST）Einstein-Hilbert Lagrangian。
We construct the pure gravity Becchi-Rouet-Stora-Tyutin (BRST) Einstein-Hilbert Lagrangian, to cubic order, using the BRST convolution product of two Yang-Mills theories, in conjunction with the Bern-Carrasco-Johansson (BCJ) double-copy.
