As far as I understand the tree level diagrams of the quantum action in QFT give the complete set of diagrams for a give process. Do the loop diagrams of the quantum action have any physical significance?
I thought maybe that by summing up all the diagrams in the quantum action might take us back to the "normal" action but after some thought this doesn't seem to be the case.
