GluonGhostVertex


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 four-momentum). The dimension and the name of the coupling constant are determined by the options Dimension and CouplingConstant.
