Abstract:
We develop an algorithm for recursively constructing orthogonal multiplet bases for the color space of QCD, for any order of partons and any N$_{c}$. This recipe is then applied for explicitly constructing some of these bases. Using the bases, a corresponding set of Wigner 6j coefficients are calculated. The Wigner coefficients offer a method of using multiplet bases without resorting to the explicit expressions of the basis vectors, which lead to a significant speed-up compared to other methods of treating full color structure.
