论文摘要
简而言之，我们提出了一种基于振幅的扩展，尺寸还原技术和差分运算符的算法，以计算带有两个质量标量的树级标量 - 格拉维顿振幅，以及树级量表量表量表量子量表，具有两个质量质量尺寸和一个质量尺寸。在应用单位性方法时，这些幅度是计算两个巨大带电物体的一般相对性的牛顿后和胶后扩展的必要输入，与重力和电磁场相互作用。
In this short note, we propose an algorithm based on the expansions of amplitudes, the dimensional reduction technic and the differential operators, to calculate the tree level scalar-graviton amplitudes with two massive scalars, as well as the tree level scalar-photon-graviton amplitudes with two massive scalars and one photon. While applying the unitarity method, these amplitudes are necessary inputs for the calculation of post-Newtonian and post-Minkowskian expansions in general relativity for two massive charged objects interact with gravity and electromagnetic field.
