Physics 215 B QFT Winter 2018 Assignment

(a) Consider scattering of an electron (e−) and a positron (e) into e−e+ (so a = b in the notation above). We wish to consider the contribution to the imaginary part of the amplitude for this process which is proportional to QeQ 2 μ where Qe and Qμ are the electric charges of the electron and muon (which are in fact numerically equal but never mind that). Draw the relevant Feynman diagram, and ...
