thank you very much. However I want to stress that in the book that you have cited, the authors carefully avoid to use the standard lagrangian for the wess-zumino model. They introduce 3 different chiral superfiled and this trick eliminates the problem of the combinatorial factors (that was...

I am calculating the one loop vacuum energy in the Wess-Zumino model, and I don't get a cancellation. For sure I've messed up with the symmetry factor for the boson diagram, because in the fermion sector i have the cancellation (that is almost trivial). I an old post 2 guys were discussing of...

Hi blechman, would be very nice if you explain to me in detail with the Wess Zumino convention (identical to the nrqed's one) the cancellation of divergence at 1-loop. I know that is a quite stupid question but I'm sure that I'm doing something wrong with the symmetry factors, because in the...
