Abstract
The purely gluonic dimension-6 -violating operator recently discovered by Weinberg is identified as a color-electric dipole moment for the gluon. It can be represented in a manifestly Bose-symmetric form using Dirac algebra. This simplifies the calculation of its anomalous dimension to first order in the QCD coupling constant.
