论文摘要
我们对计算重力散射幅度的替代性,第一个量化方法进行了教学评论,对弦乐启发的方法进行了介绍,并根据这些历史性结果激发了量子场理论的全球形式,介绍了更多的工作。我们描述了这些第一个量化技术如何极大地简化这种幅度的确定,特别是减少了输入计算并导致紧凑结果的Feynman样图的数量。
We give a pedagogical review to alternative, first quantised approaches to calculating graviton scattering amplitudes, giving an introduction to string inspired approaches and presenting more recent work based on the worldline formalism of quantum field theory that is motivated by these historic results. We describe how these first quantised techniques can greatly simplify the determination of such amplitudes, in particular reducing the number of Feynman-like diagrams that enter the computation and leading to compact results.
