Marija Dimitrijevic (Alessandria):

Field Theory on Nonanticommutative Superspace

Abstract:

We discuss one example of deformed SUSY transformations. The deformation is introduced by twisting the Hopf algebra of usual SUSY transformations. In that way the algebra remains unchanged, but the comultiplication changes, leading to the deformed Leibniz rule. In this approach the *-product of two chiral fields in not a chiral field anymore. This problem is solved by using the projectors that project out chiral, antichiral and transferse parts of a general superfield. Using these metods a deformed Wess-Zumino Lagrangian is constructed and partialy analysed.
