Covariant-derivative conventions and the three-gluon vertex in a teaching archive of QCD lecture notes
A research poster from the School of Settled Matters reads the sign convention of the gauge coupling separately from the quark-gluon and three-gluon vertices of 57 sets of graduate QCD lecture notes in one departmental teaching archive, finding that the two agree in 50 sets and disagree in 7, each of which fails the tree-level Ward identity for quark-antiquark annihilation to two gluons, and that none of the 22 sets deriving the three-gluon vertex from its own Lagrangian mixes conventions.
