Abstract
The Wess-Zumino model on nonanticommutative superspace, which contains the dimension-6 term , is shown to be renormalizable to all orders in perturbation theory, upon adding and terms to the original Lagrangian. The renormalizability is possible, even with this higher-dimension operator, because the Lagrangian is not Hermitian. Such deformed field theories arise naturally in string theory with a graviphoton background.
