Proof of a new colour decomposition for QCD amplitudes
Tom Melia (UC Berkeley & LBL Berkeley)🇺🇸
Abstract
Recently, Johansson and Ochirov conjectured the form of a new colour decomposition for QCD tree-level 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 multi-quark amplitudes.
