The chirality-flow formalism for the standard model

The chirality-flow formalism for the standard model

Abstract In a recent paper we introduced the chirality-flow formalism, a method for simple and transparent calculations of Feynman diagrams based on the left- and right-chiral $$\mathfrak {sl}(2,\mathbb {C})$$ sl ( 2 , C ) nature of spacetime. While our previous work focused on massless QED and QCD...
