论文摘要
散射幅度通常被分成其颜色（SU（n））和运动学成分。由于可以使用颜色流进行描述SU（n）量规部件，因此可以预料双SU（2）运动学部分可以用手性流动来描述。在最近的两篇论文中，我们表明确实如此，引入了标准模型计算的手性 - 流形式主义。使用手性流量方法（基础上并进一步简化了旋转旋转形式形式） - Feynman图可以直接写入Lorentz-Invariant Spinor Inner产品方面，从而允许从Feynman图到一个复杂数字的最简单，最直接的路径。在本演讲中，我们介绍了此方法并显示了一些示例。
Scattering amplitudes are often split up into their color (su(N)) and kinematic components. Since the su(N) gauge part can be described using flows of color, one may anticipate that the double su(2) kinematic part can be described in terms of flows of chirality. In two recent papers we showed that this is indeed the case, introducing the chirality-flow formalism for standard model calculations. Using the chirality-flow method -- which builds on and further simplifies the spinor-helicity formalism -- Feynman diagrams can be directly written down in terms of Lorentz-invariant spinor inner products, allowing the simplest and most direct path from a Feynman diagram to a complex number. In this presentation, we introduce this method and show some examples.
