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.
