Cancellation of vacuum energy in Wess-Zumino model

    Has anyone worked out explicitly the cancellation of the vacuum energy in the Wess-Zumino model, to order g^2 (order g is trivially zero). I get a partial cancellation but there is a piece left-over. And it's not just a question of mayeb getting a sign wrong in one diagram, or a factor of 2 off...no mater how much I would fudge any coefficient of the terms I get, there is no way to get this piece to go away. By the way, I have done and checked the one-loop correction to the scalar particles, so I don't think I am missing something really obvious (but who knows!).

    Has anyone done this calculation or seen some details provided in some reference??

    Thanks in advance,
