Abstract

Using a superfield generalization of the tadpole method, we study the one-loop effective potential for a Wess-Zumino model modified by a higher derivative term, inspired by the Lee-Wick model. The one-loop Kahlerian potential is also obtained by other methods and compared with the effective potential. (AU)
