Phys. Rev. Lett. 91, 201601 (2003) [3 pages]N=1/2 Wess-Zumino Model Is RenormalizableReceived 23 July 2003; published 12 November 2003 The Wess-Zumino model on N=1/2 nonanticommutative superspace, which contains the dimension-6 term F3, is shown to be renormalizable to all orders in perturbation theory, upon adding F and F2 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. © 2003 The American Physical Society URL:
