College Pk: Amer Physical Soc, v. 77, n. 12, p. 7, 2008.1550-7998http://hdl.handle.net/11449/24394We 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 Kahler potential in the Wess-Zumino model is worked out.7engArtigo10.1103/PhysRevD.77.125020WOS:000257290600131Acesso abertoWOS000257290600131.pdf
