Chirality-flow formalism

by Andrew Lifson

Europe/Stockholm
Description

In this talk I introduce the chirality-flow method, a method for simple and transparent calculations of Feynman diagrams based on the left and right chiral decomposition of spacetime. This method, which builds upon the spinor-helicity method, allows a single-line journey from Feynman diagram to complex number. In this talk I show why it is valid, and demonstrate how to use it in both massless and massive amplitudes.
