Resumo
We introduce and discuss the method of linear delta expansion for the calculation of effective potentials in superspace, by adopting the improved version of the super-Feynman rules. Calculations are carried out up to two loops and an expression for the optimized Kähler potential in the Wess-Zumino model is worked out. © 2008 The American Physical Society.
