Proof of a new colour decomposition for QCD amplitudes
arXiv:1509.03297 · doi:10.1007/JHEP12(2015)107
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.
