引力子与自旋 1 物质的相互作用与众所周知的光子情况并行计算。结果表明，引力子散射振幅可以分解为熟悉的电磁形式的乘积，并且可以使用螺旋度方法直接评估各种反应的横截面。确定了普遍性关系。外推到零质量会产生光子-引力子和引力子-引力子散射的散射振幅。从不同的角度讨论了通常使用经典广义相对论处理的大质量物体附近的光弯曲现象。
The interactions of gravitons with spin-1 matter are calculated in parallel with the well known photon case. It is shown that graviton scattering amplitudes can be factorized into a product of familiar electromagnetic forms, and cross sections for various reactions are straightforwardly evaluated using helicity methods. Universality relations are identified. Extrapolation to zero mass yields scattering amplitudes for photon-graviton and graviton-graviton scattering. The phenomenon of light bending near a massive object, which is generally treated using classical general relativity, is discussed from alternative points of view.
