Field Theory on Nonanticommutative Superspace

We discuss a deformation of the Hopf algebra of supersymmetry (SUSY) transformations based on a special choice of twist. As usual, algebra itself remains unchanged, but the comultiplication changes. This leads to the deformed Leibniz rule for SUSY transformations. Superfields are elements of the algebra of functions of the usual supercoordinates. Elements of this algebra are multiplied by using...

N = 2 Chiral Wznw Model in Superspace

We study the Poisson bracket algebra of the N = 2 supersymmetric chiral WZNW model in superspace. It involves two classical r-matrices, one of which comes from the geometrical constraints implied by N = 2 supersymmetry. The phase space itself consists of superfields satisfying constraints involving this r-matrix. An attempt is made to relax these constraints. The symmetries of the model are inv...

SYM theories and supergauge invariance

So far, quantum properties of N = 1/2 nonanticommutative (NAC) super Yang– Mills theories have been investigated in the WZ gauge. The gauge independence of the results requires assuming that at the quantum level supergauge invariance is not broken by nonanticommutative geometry. In this paper we use an alternative approach which allows studying these theories in a manifestly gauge independent s...

Quantum Algebra of N Superspace

We identify the quantum algebra of position and momentum operators for a quantum system bearing an irreducible representation of the super Poincaré algebra in the N extended superspace. This algebra is noncommutative for the position operators. We use the properties of superprojectors in D = 4 N superspace to construct explicit position and momentum operators satisfying the algebra. They act on...

Partial Supersymmetry Breaking and N = 2 U ( N c ) Gauge Model with Hypermultiplets in Harmonic Superspace

We provide a manifestly N = 2 supersymmetric formulation of the N = 2 U(Nc) gauge model constructed in terms of N = 1 superfields in hep-th/0409060. The model is composed of N = 2 vector multiplets in harmonic superspace and can be viewed as the N = 2 U(Nc) Yang-Mills effective action equipped with the electric and magnetic Fayet-Iliopoulos terms. We generalize this gauge model to an N = 2 U(Nc...
