Birdtracks of exotic SU(N) color structures

Thorsten Ohl (Institute of Theoretical Physics and Astrophysics, University of Würzburg, Emil-Hilb-Weg 22, Würzburg, 97074, Germany)

I introduce a systematic procedure for constructing complete and linearly independent sets of color structures for interactions of fields transforming under exotic representations of SU(N), in particular the SU(3) gauge group of QCD. It uncovers errors in previous results, starting with interactions of four fields including a single sextet.
