1. The problem statement, all variables and given/known data
Draw the Feynman diagram vertex corresponding to the interaction Lint = eAμJμ,
where Aμ is the electromagnetic field and e is the coupling constant. Draw all the Feynman
diagrams in quantum electrodynamics to O(e2) describing the processes:
(i) e+e- ----> e+e-,
(ii) e+e- ----> μ+μ-
(iii)γ e- ------> γ e-

2. Relevant equations

Any ideas on how i should approach this question?
