Invert the kinetic operators that appear in the action to find the propagators for the ghost field and for the gluon therefore the photon propagator is again GA

where, in deriving this, we need the completeness relation for the polarization work in front of us in order to massage the photon propagator into something

7 Quantization of the Photon Field

To obtain the Feynman propagator in the Coulomb gauge no new derivation is required The result can be taken from Sect 7 5, i e , (here we reinstate the
