我们利用引力康普顿散射振幅分解成阿贝尔QED振幅的特征来评价各种引力康普顿过程。我们用螺旋振幅法研究了一个大质量自旋-1系统的QED和引力康普顿散射。在引力康普顿散射的情况下，我们展示了如何使用无质量极限来评估引力子-光子散射的横截面，并讨论了光子相互作用与零质量自旋-1极限之间的区别。我们证明了引力子光产生的前向散射截面具有非常特殊的行为，不同于类似库仑势的标准汤姆逊和卢瑟福截面。
We use the feature that the gravitational Compton scattering amplitude factorizes in terms of Abelian QED amplitudes to evaluate various gravitational Compton processes. We examine both the QED and gravitational Compton scattering from a massive spin-1 system by the use of helicity amplitude methods. In the case of gravitational Compton scattering we show how the massless limit can be used to evaluate the cross section for graviton-photon scattering and discuss the difference between photon interactions and the zero mass spin-1 limit. We show that the forward scattering cross section for graviton photoproduction has a very peculiar behavior, differing from the standard Thomson and Rutherford cross sections for a Coulomb-like potential.
