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...
متن کاملChiral zero modes of the SU(n) WZNW model
We define the chiral zero modes’ phase space of the G = SU(n) Wess-Zumino-Novikov-Witten (WZNW) model as an (n − 1)(n + 2)dimensional manifoldMq equipped with a symplectic form Ωq involving a Wess-Zumino (WZ) term ρ which depends on the monodromy M and is implicitly defined (on an open dense neighbourhood of the group unit) by dρ(M) = 1 3 tr (MdM) . (∗) This classical system exhibits a Poisson-...
متن کاملChiral Models in Noncommutative N =1/2 Four Dimensional Superspace
We derive the component Lagrangian for a generic N = 1/2 supersymmetric chiral model with an arbitrary number of fields in four space-time dimensions. We then investigate a toy model in which the deformation parameter modifies the undeformed potential near the origin of the field space in a way which suggests possible physical applications.

متن کاملExtended chiral algebras in the SU (2)0 WZNW model
We investigate the W-algebras generated by the integer dimension chiral primary operators of the SU(2)0 WZNW model. These have a form almost identical to that found in the c = −2 model but have, in addition, an extended Kac-Moody structure. Moreover on Hamiltonian reduction these SU(2)0 W -algebras exactly reduce to those found in c = −2. We explicitly find the free field representations for th...
متن کاملThe Mini - Superspace Limit of the Sl ( 2 , C ) / Su ( 2 ) - Wznw Model
Many qualitatively new features of WZNW models associated to noncompact cosets are due to zero modes with continuous spectrum. Insight may be gained by reducing the theory to its zero-mode sector, the mini-superspace limit. This will be discussed in some detail for the example of SL(2,C)/SU(2)-WZNW model. The mini-superspace limit of this model can be formulated as baby-CFT. Spectrum, structure...
