Abstract:
Calculations involving the SU(3) structure of QCD are typically performed using so-called trace bases or color flow bases for decomposing color structure. While these spanning sets have some simplifying properties, the fact that they are overcomplete and non-orthogonal becomes a major obstacle for calculations involving many partons. In this talk I will describe how to use group invariants to perform color space calculations instead, and I will argue that this --- once a sufficient set of invariants and an efficient implementation is at hand --- may well be superior.
