Proof of a new colour decomposition for QCD amplitudes
Abstract
Recently, Johansson and Ochirov conjectured the form of a new colour decomposition for QCD treelevel amplitudes. This note provides a proof of that conjecture. The proof is based on ‘Mario World’ Feynman diagrams, which exhibit the hierarchical Dyck structure previously found to be very useful when dealing with multiquark amplitudes.
