ScalarGluonVertex

    or ScalarGluonVertex[ p, q, mu, a ] yields the scalar-scalar-gluon vertex (p and q are incoming momenta). ScalarGluonVertex[{mu,a}, {nu,b}] yields the scalar-scalar-gluon-gluon vertex (p and q are incoming momenta).     The dimension and the name of the coupling constant are determined by the options Dimension and CouplingConstant.
