ColorMath - A package for color summed calculations in SU(Nc)

Abstract

A Mathematica package for color summed calculations in QCD (SU(Nc)) is presented. Color contractions of any color amplitude appearing in QCD may be performed, and the package uses a syntax which is very similar to how color structure is written on paper. It also supports the definition of color vectors and bases, and special functions such as scalar products are defined for such color tensors.

14 pages, published in EPJC, new package version tested also with Mathematica 9, minor typo corrections
