This should be a useful reference for anybody with an interest in quantum theory.The associated vacuum diagram in the theory with a source is def Dj = We can write the amplitudes for these ... we apply D to I (D1). we find that there are 4! terms corresponding to the 4! ways of assigning momenta to the lines in D. Now, sinceanbsp;...
