Homework Statement This is not homework but relevant to an interaction model that I am developing. I assume an even distribution of sources on a spherical 3d-hypersurface, the sources having a potential as a function of pairwise 4-distance between any two sources. I wish to obtain the sum...

Those of you who may know the unitary method: is the essence here that there is some kind of pairwise cancellation of terms at distance if gravity amplitude is depicted as cited above Feynman diagrams are used to calculate outcomes of electro-weak interactions as well, aren't they? What...
