Two-Loop Effective Potential
for Wess-Zumino Model using Superfields

artigo 'Two-Loop Effective Potential for Wess-Zumino Model using Superfields'Two-Loop Effective Potential for Wess-Zumino Model using superfields. (with SRIVASTAVA, P.P.) Brazilian Journal of Physics, v. 19, n. 1, pp. 7-26, 1989.

For the case of several interacting chiral superfields the propagators for the unconstrained superfield potentials in the 'shifted' theory, where the supersymmetry is explicitly broken, are derived in a compact form. They are used to compute the one-loop effective potential in the general case, while a superfield calculation of the renormalized effective potential to two loops for the Wess-Zumino madel is performed.
