Abstract
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.
