Colour: A computer program for QCD colour factor calculations

Jari Häkkinen, Hamid Kharraziha

    Research output: Contribution to journalArticlepeer-review


    A computer program for evaluating colour factors of QCD Feynman diagrams is presented, and illustrative examples on how to use the program to calculate nontrivial colour factors are given. The program and the discussion in this paper is based on a diagrammatic approach to colour factors.
