论文摘要
我们仔细研究了旋转螺旋形式主义中的Feynman图。着眼于树级无质量QED和QCD，我们为其计算开发了一种新的概念上简单的图形方法。在我们配音性形式主义的这种图形方法中，Feynman图是用与Spinor Inner产品相对应的手性流线直接表示的，而无需诉诸中间代数操纵。
We take a fresh look at Feynman diagrams in the spinor-helicity formalism. Focusing on tree-level massless QED and QCD, we develop a new and conceptually simple graphical method for their calculation. In this pictorial method, which we dub the chirality-flow formalism, Feynman diagrams are directly represented in terms of chirality-flow lines corresponding to spinor inner products, without the need to resort to intermediate algebraic manipulations.
