GluonGhostVertex

GluonGhostVertex[{p, mu, a}, {q, nu, b}, {k, rho, c}] or GluonGhostVertex[ p, mu, a , q, nu, b , k, rho, c] yields the Gluon-Ghost vertex. The first argument represents the gluon and the third argument the outgoing ghost field (but incoming 4-momentum).

GGV can be used as an abbreviation of GluonGhostVertex.The dimension and the name of the coupling constant are determined by the options Dimension and CouplingConstant.
