Title: | Twisted supersymmetry: Twisted symmetry versus renormalizability | Authors: | Dimitrijević-Ćirić, Marija Nikolić, Biljana Radovanović, Voja |
Issue Date: | 7-Mar-2011 | Journal: | Physical Review D - Particles, Fields, Gravitation and Cosmology | Abstract: | We discuss a deformation of superspace based on a Hermitian twist. The twist implies a -product that is noncommutative, Hermitian and finite when expanded in a power series of the deformation parameter. The Leibniz rule for the twisted supersymmetry transformations is deformed. A minimal deformation of the Wess-Zumino action is proposed and its renormalizability properties are discussed. There is no tadpole contribution, but the two-point function diverges. We speculate that the deformed Leibniz rule, or more generally the twisted symmetry, interferes with renormalizability properties of the model. We discuss different possibilities to render a renormalizable model. © 2011 American Physical Society. |
