One-loop-order renormalization of the massive Wess-Zumino model in anti–de Sitter space

We calculate the one-particle-irreducible two- and three-point functions of the model and check that our regularization prescription preserves supersymmetry for the divergent one-loop corrections. It turns out that the no-renormalization theorem valid in flat space-time still holds in the four-dimensional anti–de Sitter background space, since neither the mass nor the interaction Lagrangians get renormalized. The common renormalization factor that, multiplied times the kinetic action, gives the effective action is calculated.
