Abstract We take a fresh look at Feynman diagrams in the spinor-helicity formalism.Focusing on tree-level massless QED and bioglan deep sleep QCD, we develop a new and conceptually simple graphical method for their calculation.In this pictorial method, which we dub the syil x5 price 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.
