摘要：

We present a decomposition of one-loop amplitudes in pure SU(N) gauge theories into a sum of products of traces of charge matrices and color-independent kinematic factors. The decomposition is the one-loop extension of the cyclic color decomposition that has come into widespread use in tree-level amplitudes.
