Description
It is well-known that the spinor-helicity method can significantly simplify the calculations of both Feynman diagrams and scattering amplitudes. In this work, we attempt to further simplify the Feynman-diagram calculation by converting the spinor-helicity method into a flow method, allowing a one-line journey from Feynman diagram to inner products. The cases of massless QED and QCD will be discussed.
